A Ford F-450 already has an imposing stance, substantial towing capability, and a heavy-duty solid front axle, but the factory front-to-rear rake is not ideal for every owner. Installing the best F450 leveling kit can raise the front, reduce the nose-down appearance, create additional tire clearance, and give the truck a more balanced stance without moving to a full suspension lift.
The F-450 also demands more careful kit selection than a lighter pickup. Modern F-450 Super Duty trucks use a heavy front axle, dual rear wheels, and application-specific steering and suspension geometry. A kit marketed broadly for an F-250, F-350, and F-450 may physically fit several models while still requiring different alignment, caster, track-bar, wheel, or tire considerations on the F-450.
My primary recommendation is the ReadyLIFT 66-2726 2.5-Inch Super Duty Leveling Kit. I prefer it when a compatible 4WD F-450 needs a comprehensive spacer-based level because it includes front coil spacers, shock extensions, sway-bar correction components, and a track-bar relocation bracket rather than addressing ride height alone.
I would consider the maXpeedingrods GO90QA 2.5-Inch Front Leveling Kit for a compatible 2011–2022 4WD truck when a complete hardware package at a different price point is more important. It also incorporates track-bar correction, shock extensions, and sway-bar spacing rather than supplying only simple coil spacers.
The ReadyLIFT 66-2725 2.5-Inch Front Leveling Kit is the alternative I would consider when the truck’s axle position and alignment requirements allow the simpler configuration. It raises the front while retaining the factory coils and includes shock and sway-bar correction components, but it does not provide the same track-bar relocation solution as the 66-2726.
Before choosing among them, measure the truck’s current rake and verify the exact model year, 4WD configuration, pickup versus cab-and-chassis application, rear block height, front axle arrangement, and wheel/tire plan.

1. ReadyLIFT 66-2726 2.5-Inch Super Duty Leveling Kit
Key Features
- Approximately 2.5 inches of front lift
- Designed for compatible Super Duty 4WD applications
- Intended for trucks using the appropriate factory rear block
- Front coil spring spacer configuration
- Track-bar relocation bracket included
- Shock extensions included
- Sway-bar spacing components included
- Sound isolators included
- Supports larger tire combinations when wheel offset and clearance permit
- Requires application-specific attention on 10-lug F-450 trucks
The ReadyLIFT 66-2726 takes the first position because it addresses more of the suspension geometry affected by a substantial front level than a basic two-spacer kit.
Raising a solid-front-axle Super Duty by 2.5 inches does more than move the body upward. The front axle is controlled laterally by a track bar, and that bar travels through an arc as ride height changes. When the chassis moves upward relative to the axle, a fixed track-bar arrangement can pull the axle sideways.
That is one reason I prefer a leveling system that considers axle position rather than focusing only on coil height.
The 66-2726 includes a track-bar relocation bracket designed to help correct the altered relationship between the axle and chassis. This matters for steering feel, axle centering, tire position within the wheel openings, and alignment.
The kit also includes shock extensions. Raising the suspension without considering shock operating range can leave the factory shocks sitting in a less favorable position within their travel. Extensions reposition the shock mounting relationship so the existing shocks can continue operating with the lifted ride height.
ReadyLIFT also includes sway-bar spacing components. The anti-roll bar, commonly called a sway bar, connects the left and right sides of the front suspension and helps control body roll. Changing suspension height alters its operating angle, so correcting that relationship is preferable to simply installing coil spacers and leaving every connected component in its original position.
The 2.5-inch lift amount is substantial enough to make a visible difference on an F-450. It can reduce factory rake and create additional room around the front tires.
That does not mean every F-450 will sit perfectly level after installation.
Factory rake varies according to:
- Model year
- Pickup or cab-and-chassis configuration
- Engine
- Front accessory weight
- Rear spring package
- Rear block height
- Fuel and cargo load
- Installed towing equipment
Measure before ordering.
Park the truck on level ground and measure vertically through the wheel center from a consistent point on the front and rear fenders. The difference gives you a useful estimate of the existing rake.
If the front measures only 1.5 inches lower than the rear, installing a full 2.5-inch level may create a slight nose-high stance when unloaded. That becomes even more noticeable when a heavy trailer adds tongue or pin weight to the rear suspension.
F-450 owners also need to pay particular attention to caster.
Caster describes the forward or rearward tilt of the steering axis when viewed from the side. Proper positive caster contributes to straight-line stability and steering-wheel return.
Changing ride height can change caster. A heavy truck that spends hours towing at highway speed should not have its alignment treated as an afterthought.
Another important detail is the F-450’s 10-lug front configuration on relevant pickup applications. Some caster-correction hardware associated with broader Super Duty leveling systems is not applicable to 10-lug trucks. That does not automatically make the entire kit unusable, but it means an F-450 owner should verify the correct caster-correction strategy rather than assuming every F-250/F-350 alignment component transfers directly.
I would have the truck professionally aligned after installation and specifically request measurements for:
- Caster
- Toe
- Steering-wheel position
- Front axle centering
Do not accept “the steering wheel looks straight” as a complete post-installation alignment assessment.
Tire clearance also needs context.
A leveling kit can create room for larger tires, but the tire diameter is only part of the equation. Width and wheel offset determine where the tire sits relative to the suspension, radius arms, inner fender, and outer bodywork.
The F-450’s factory wheel and tire arrangement is also very different from the aftermarket 20- and 22-inch wheel combinations commonly seen on modified trucks. If changing away from the factory commercial-style wheel setup, make sure every new wheel and tire has adequate load capacity for the truck’s actual axle ratings and intended towing use.
What I Like
- Addresses axle geometry with a track-bar relocation bracket
- Includes shock extensions rather than ignoring shock position
- Includes sway-bar correction components
- Provides a meaningful 2.5-inch front stance change
- Retains the factory front coil springs
- More complete than a basic spacer-only leveling solution
What I Do Not Like
- F-450 10-lug applications require additional attention to caster correction
- 2.5 inches can be too much for trucks that have little factory rake
- Larger tires still depend on wheel width and offset
- Installation should be followed by a proper alignment
Verdict
The ReadyLIFT 66-2726 is my primary recommendation for a compatible F-450 because it treats leveling as a suspension-geometry change rather than simply adding height. The track-bar, shock, and sway-bar provisions make it the most complete spacer-based package of these three.
I would choose it only after measuring actual rake and confirming the correct F-450-specific caster and axle-centering procedure for the truck.
2. maXpeedingrods GO90QA 2.5-Inch Front Leveling Kit
Key Features
- 2.5-inch front lift
- Designed for compatible 2011–2022 F-450 Super Duty 4WD applications
- High-strength steel primary components
- Protective powder-coated finish
- Front coil spring spacers
- Track-bar relocation bracket
- Shock extensions
- Sway-bar spacers
- Sound-isolation components
- Hardware package included
- Intended to work with trucks using the appropriate factory rear block
The maXpeedingrods GO90QA follows a similar overall design philosophy to the ReadyLIFT package: raise the truck at the front while providing supporting components for the other suspension systems affected by the height change.
Its manufacturer-listed application includes compatible 2011–2022 F-450 Super Duty 4WD trucks, making the year range narrower than some current-generation alternatives. That can actually be helpful because it encourages buyers to treat fitment as vehicle-specific instead of assuming one leveling kit fits every F-450 ever produced.
The kit uses steel coil-spacer components and a corrosion-resistant coated finish. On a heavy-duty truck, material choice matters because the front suspension supports substantial engine and chassis weight.
The spacers retain the original coil springs instead of replacing them with longer aftermarket coils.
That approach has one major advantage: you keep the factory spring-rate characteristics. A spacer changes static ride height, but it does not inherently turn the stock coil into a softer or stiffer spring.
That helps explain why spacer kits can preserve much of the familiar factory ride when the rest of the suspension geometry is corrected appropriately.
The downside is that a spacer cannot improve the spring itself.
If your F-450’s front coils are tired, sagging, or poorly suited to additional front-end weight from a heavy bumper, winch, or other equipment, a longer purpose-built spring system may be a more logical solution.
The GO90QA includes a track-bar relocation bracket, which I consider one of its most valuable features.
A track bar that remains in its original position after a 2.5-inch height change can shift the axle laterally. That shift may be small in measurement but still relevant to steering geometry and tire position.
This kit also provides shock extensions, allowing use of the existing shocks when they remain in good condition.
I would inspect the shocks before reusing them.
Look for:
- Oil leakage
- Damaged shafts
- Worn bushings
- Corrosion
- Excessive bounce
- Deteriorated mounting hardware
Leveling a truck does not restore an old shock absorber. If the shocks are already near the end of their life, installing suitable longer-travel replacements during the same service can be more efficient.
The sway-bar spacing hardware helps reposition the bar after the front is raised.
Brake-line and ABS-wire routing also deserve inspection during installation. Cycle the steering from lock to lock and inspect the suspension at normal ride height to ensure no hose, wire, or line is being stretched or pulled into contact with moving components.
One limitation is the 2011–2022 application range. Owners of newer trucks should not assume compatibility because the truck looks similar.
Later Super Duty trucks can include different electronic equipment and suspension-related systems, including Onboard Scales and automatic headlight-leveling considerations on certain configurations.
I also would not automatically assume that a listed maximum tire diameter guarantees rub-free operation.
A 35×12.50 tire on one wheel can fit differently from the same tire on another wheel because offset changes both inner and outer clearance.
F-450 owners converting from the factory wheel setup need to pay especially close attention to wheel load rating.
The truck’s towing and payload capability places far greater demands on wheels and tires than appearance-focused light-truck builds.
What I Like
- Complete 2.5-inch spacer-based leveling package
- Includes track-bar correction
- Retains factory coil springs
- Includes shock and sway-bar correction components
- Steel construction suits a heavy-duty suspension application
- Clearly defined 2011–2022 4WD fitment range
What I Do Not Like
- Does not cover every newer F-450 model year
- Factory shocks are retained unless upgraded separately
- Exact tire clearance still depends on wheel specifications
- Professional alignment remains necessary after installation
Verdict
I would consider the maXpeedingrods GO90QA when leveling a compatible 2011–2022 F-450 4WD and wanting a fairly comprehensive spacer-style package.
It earns second place because it addresses the major supporting geometry rather than supplying only front spacers, but I would still give the ReadyLIFT 66-2726 the advantage for my primary recommendation.
3. ReadyLIFT 66-2725 2.5-Inch Front Leveling Kit
Key Features
- 2.5-inch maximum front lift
- Designed for compatible Super Duty 4WD applications
- Front coil spacer configuration
- Uses factory front coil springs
- Sound isolators included
- Shock extensions included
- Sway-bar spacers included
- Supports larger tire combinations when properly configured
- Simpler package than the 66-2726
- Does not include the same track-bar relocation bracket
The ReadyLIFT 66-2725 is the simpler alternative to the first product.
It still provides approximately 2.5 inches of front lift and addresses shock and sway-bar positioning, but it does not include the track-bar relocation bracket supplied with the 66-2726.
That difference matters more on a solid-axle F-450 than it might appear from the parts list.
When the front suspension is lifted, the track bar’s angle changes. Depending on the truck’s starting geometry, that can move the axle laterally.
Some trucks may remain acceptably centered with the factory arrangement, while another truck may benefit from a relocation bracket or an adjustable track bar.
That is why I see the 66-2725 as better suited to owners who are prepared to measure axle position and add the appropriate correction separately if required.
The spacer arrangement retains the factory springs.
For an F-450 used predominantly on pavement, that can be appealing because the owner may want the stance and tire clearance of a level without changing the underlying spring rate.
The supplied shock extensions are useful when retaining functional stock-length shocks.
Sway-bar spacing is also included to improve the bar’s position after the height change.
As with the other 2.5-inch kits, though, advertised tire clearance is not a substitute for checking actual wheel geometry.
F-450 tire fitment can become complicated because owners may be moving from the factory dually wheel configuration to aftermarket wheels specifically to gain access to different tire sizes.
Check:
- Front wheel width
- Wheel offset
- Backspacing
- Tire section width
- Radius-arm clearance
- Fender clearance at full steering lock
- Wheel load capacity
- Tire load index
Do not sacrifice load capacity simply to achieve a particular appearance.
This is especially important if the truck still performs the work that justified buying an F-450 in the first place.
For newer trucks equipped with Onboard Scales or automatic headlight-leveling equipment, additional correction hardware may be necessary after changing ride height.
A suspension modification physically changes the relationship between the truck body, axle, and road. Systems designed to interpret vehicle attitude can therefore require application-specific adjustment.
Another consideration is towing rake.
Ford gives heavy-duty trucks a rear-high stance partly because the rear suspension compresses under load.
If you completely eliminate that rake while the truck is empty, adding significant fifth-wheel or gooseneck pin weight can leave the front visibly higher than the rear.
For a dedicated towing truck, I often prefer leaving a modest amount of unloaded rake rather than chasing a perfectly level parking-lot stance.
That may mean choosing a smaller lift height or correcting rear load support separately when appropriate.
What I Like
- Straightforward 2.5-inch front level
- Keeps the factory front coils
- Shock extensions included
- Sway-bar correction included
- Appropriate for owners who want a simpler system
- Useful when track-bar correction will be handled separately
What I Do Not Like
- No included track-bar relocation bracket
- Axle centering must receive extra attention
- Full 2.5-inch lift may be excessive for some towing-focused trucks
- Larger tires can require different wheels and additional clearance work
Verdict
The ReadyLIFT 66-2725 is my third choice because it provides the core components needed for a 2.5-inch front level but leaves track-bar correction less comprehensively addressed than the first two options.
I would choose it when I had already evaluated axle centering and planned to use the appropriate track-bar solution for that specific F-450.
F450 Leveling Kit Comparison
| Product | Front Lift | Suspension Type | Track-Bar Correction | Shock Solution | Sway-Bar Correction | Main Fitment | Main Strength | Main Limitation |
| ReadyLIFT 66-2726 | 2.5 in. | Coil spacer | Relocation bracket included | Extensions | Included | Compatible Super Duty F-450 4WD | Most complete geometry package | 10-lug caster details require attention |
| maXpeedingrods GO90QA | 2.5 in. | Coil spacer | Relocation bracket included | Extensions | Included | 2011–2022 F-450 4WD | Complete alternative package | Narrower model-year range |
| ReadyLIFT 66-2725 | 2.5 in. | Coil spacer | Not included in same configuration | Extensions | Included | Compatible F-450 4WD applications | Simple factory-coil solution | Track-bar correction may need separate solution |
The ReadyLIFT 66-2726 stands out because it combines the leveling spacers with more comprehensive front-axle geometry correction.
The maXpeedingrods kit uses a similar component strategy for compatible 2011–2022 trucks, while the ReadyLIFT 66-2725 is better viewed as a simpler starting point for an owner who understands that axle position may need additional attention.
How to Choose the Best F450 Leveling Kit
Measure Your Factory Rake Before Ordering
Do not assume your F-450 needs exactly 2.5 inches.
Park on flat pavement and measure the front and rear ride height through the centerline of the wheels using consistent body reference points.
If the rear is 2.5 inches higher, a 2.5-inch front level may produce approximately the stance you want.
If the difference is only 1.5 inches, a full 2.5-inch lift could leave the front higher.
Remember that fuel, tools, auxiliary tanks, fifth-wheel equipment, and permanently carried cargo can change these measurements.
Decide Whether You Still Need Towing Rake
A perfectly level unloaded truck is not necessarily ideal for towing.
Factory rake gives the rear suspension room to compress under load without immediately producing a nose-high attitude.
If your F-450 regularly pulls a large fifth-wheel or gooseneck trailer, leaving approximately some amount of unloaded rake can be more practical than leveling solely for appearance.
A work truck and a show-oriented truck do not necessarily need the same suspension setup.
Understand the F-450’s Track Bar
The track bar locates the solid front axle from side to side.
When ride height changes, the bar moves through an arc and can shift the axle laterally.
A relocation bracket changes the mounting relationship to compensate. An adjustable track bar takes a different approach by allowing the effective bar length to be changed.
Either can work when properly engineered for the application.
The important point is not to ignore axle position.
Caster Matters on a Heavy Truck
Caster strongly influences highway stability and steering return.
Raising the front suspension can change caster, which is why post-installation alignment is essential.
An F-450 that tows heavy loads at interstate speeds deserves precise steering geometry.
Pay particular attention to whether the caster-correction hardware supplied with a general Super Duty kit actually applies to your 10-lug F-450.
Check 4WD Fitment
The products reviewed here are focused primarily on compatible 4WD Super Duty applications.
Do not install a 4WD-specific coil-spacer system on a 2WD truck simply because the model and engine match.
Front suspension architecture determines fitment.
Pickup vs. Cab and Chassis
F-450 pickup and F-450 cab-and-chassis trucks are not automatically identical from a suspension standpoint.
Cab-and-chassis models may use different:
- Spring rates
- Rear suspension configurations
- Axle arrangements
- Wheelbases
- Ride heights
- GVWR packages
Confirm the exact application before purchasing suspension components.
Choosing Tires After Leveling an F450
Leveling is frequently performed to create additional room for larger tires, but F-450 owners face a unique issue: the factory wheel and tire package is designed around commercial-duty load requirements.
A 35-inch tire may physically fit after leveling, but that does not automatically make it suitable.
Check the tire’s load index and the wheel’s rated capacity.
The replacement setup needs adequate capacity for the vehicle’s:
- Front gross axle weight rating
- Rear gross axle weight rating
- Loaded operating weight
- Towing configuration
A wheel that looks impressive but cannot safely support the truck’s rated load is the wrong wheel.
Wheel Offset Changes Clearance
Wheel offset is the distance between the wheel’s mounting surface and its centerline.
Moving the tire outward can increase clearance from suspension components but may increase contact with the outer fender.
Moving it inward does the opposite.
This is why one 35-inch tire can fit while another apparently identical 35-inch setup rubs.
Check Clearance at Full Steering Lock
After changing wheels or tires:
- Turn fully left.
- Inspect inner and outer clearance.
- Turn fully right.
- Repeat the inspection.
- Check clearance with the suspension loaded where possible.
Look around the radius arms, inner liners, bumper area, and suspension components.
Installation Considerations
An F-450 is extremely heavy. Use lifting equipment and jack stands appropriately rated for the actual truck weight.
Do not rely on equipment intended for a light passenger vehicle.
Leveling-kit installation typically requires unloading the front coil springs enough to install the new spacers. The track bar, shocks, sway bar, and related brackets may also require disconnection.
Brake hoses and ABS wiring must remain free of tension throughout suspension and steering movement.
After installation:
- Torque all fasteners correctly
- Confirm spring seating
- Check track-bar hardware
- Check brake-line routing
- Check ABS wiring
- Inspect shock mounting
- Center the steering wheel
- Perform a professional alignment
- Recheck critical fasteners after initial driving
Suspension hardware is safety-critical. Installation quality matters as much as the kit itself.
2023 and Newer F450 Considerations
Newer Super Duty trucks can include Onboard Scales and automatic headlight-leveling systems.
Changing suspension height can affect how these systems interpret vehicle attitude.
Compatible correction hardware may therefore be required.
Do not assume a leveling kit designed before those features appeared is automatically complete for a newer truck.
Verify the kit instructions for your exact model year and factory options.
Will an F450 Leveling Kit Change Ride Quality?
A spacer kit generally retains the factory spring rate because the original coil spring remains in place.
That does not mean ride quality is guaranteed to remain completely unchanged.
Ride and handling can also be influenced by:
- Shock position
- Caster
- Track-bar angle
- Sway-bar angle
- Tire sidewall
- Wheel weight
- Tire pressure
- Unsprung mass
In many modified F-450s, changing from factory commercial-style tires to large aftermarket tires has a greater effect on steering and ride feel than the spacer itself.
Common Mistakes When Leveling an F450
Buying an F250 Kit Without Checking F450 Details
Shared Super Duty architecture does not make every alignment or caster component identical.
Installing 2.5 Inches Without Measuring
Some trucks need less lift to achieve the desired stance.
Ignoring Track-Bar Geometry
A shifted solid axle can affect wheel position and steering.
Skipping the Alignment
Toe and caster should be checked after changing front ride height.
Choosing Tires Only by Diameter
Width, offset, wheel capacity, and load index are equally important.
Removing All Factory Rake on a Heavy Tow Vehicle
The truck may become nose-high once trailer weight compresses the rear suspension.
Ignoring Newer Electronic Systems
Onboard weighing and headlight-leveling equipment may require additional correction.
Frequently Asked Questions
What is the best F450 leveling kit?
The best kit combines correct lift height with proper track-bar, shock, sway-bar, and alignment correction.
I prefer the ReadyLIFT 66-2726 for a compatible F-450 because it provides a comprehensive 2.5-inch spacer-based system with a track-bar relocation bracket. However, exact model year, 10-lug caster requirements, factory rear block, and intended towing use must be confirmed first.
How much leveling does an F450 need?
Many owners consider roughly 1.5 to 2.5 inches, but actual rake should determine the height.
Measure the truck before purchasing a kit. Factory ride height varies with model year, spring package, installed equipment, and load. A 2.5-inch kit can look correct on one truck and slightly nose-high on another.
Can I put a 2.5-inch leveling kit on an F450?
Yes, compatible F-450 4WD applications can use 2.5-inch front leveling systems.
The installation must address front axle position, caster, shock range, sway-bar geometry, brake-line clearance, and alignment. Verify that the specific kit supports your model year and configuration.
Can I fit 35-inch tires after leveling my F450?
Often yes, but lift height alone cannot guarantee 35-inch tire clearance.
Wheel width, offset, tire width, suspension clearance, and body clearance all matter. F-450 owners must also verify that replacement wheels and tires have sufficient load capacity for the truck.
Will a leveling kit hurt F450 towing?
A properly installed kit does not eliminate towing capability, but removing rake can change loaded stance.
A truck that sits perfectly level while empty may become rear-low when significant tongue or pin weight is applied. Heavy towing users should consider how much factory rake they actually want to remove.
Does an F450 need an alignment after leveling?
Yes, a professional alignment should follow any significant front suspension height change.
Ask the technician to check caster and toe rather than simply centering the steering wheel. Front axle centering should also be verified on a solid-axle truck.
Why does an F450 leveling kit need a track-bar bracket?
A track-bar correction system helps compensate for lateral axle movement caused by changed ride height.
The track bar moves in an arc. Raising the chassis can therefore shift the solid axle sideways. Relocation brackets or adjustable track bars help restore the intended relationship.
Does a spacer leveling kit make the suspension stiffer?
The spacer itself does not increase the factory coil spring rate.
Because the original spring remains, its basic rate remains unchanged. Ride can still feel different because alignment, shocks, sway-bar geometry, wheel weight, and tire construction may change.
Can I keep factory shocks with a leveling kit?
Yes, some kits use shock extensions specifically to retain serviceable factory-length shocks.
Inspect the existing shocks before reuse. If they are leaking, worn, or already need replacement, suitable shocks designed for the new ride height may be the better long-term choice.
Is an F450 leveling kit good for a truck with a snowplow or heavy bumper?
It can restore front ride height, but replacement springs may be better for substantial permanent weight.
A spacer raises the existing spring without increasing its spring rate. If heavy front accessories have caused significant sag, properly rated replacement coils may provide a more complete solution.
Do 2023 and newer F450 trucks need extra parts when leveling?
Some trucks with Onboard Scales or automatic headlight leveling require additional correction hardware.
Check your factory option list and the leveling-kit instructions. Suspension-height changes can affect systems that measure or respond to vehicle attitude.
Is a 2.5-inch level better than a 1.5-inch level?
Neither is universally better; the correct height depends on the truck’s actual rake and use.
A 1.5-inch level preserves more rear-high stance for towing, while 2.5 inches produces a more dramatic unloaded level and additional front clearance.
Can I level an F450 myself?
Experienced DIY mechanics can perform the work, but the truck’s weight and suspension forces demand proper equipment.
Use appropriately rated lifting equipment and follow the installation procedure carefully. A professional alignment is still necessary after installation, even if the mechanical work is completed at home.
Will leveling increase ground clearance?
It increases front body and chassis clearance but does not automatically raise the differential.
The solid front axle’s differential remains determined largely by tire radius. Larger tires increase differential clearance, while a coil-spacer level primarily raises the chassis relative to the axle.
Conclusion
Choosing the best F450 leveling kit requires more than deciding how high you want the front bumper to sit. The F-450’s solid front axle, 10-lug configuration, heavy towing role, wheel and tire load requirements, and application-specific alignment needs make suspension geometry especially important.
The ReadyLIFT 66-2726 remains my primary recommendation for a compatible truck because its 2.5-inch front lift is supported by a track-bar relocation bracket, shock extensions, sway-bar correction, and related hardware. That makes it the most complete spacer-based solution among these three.
The maXpeedingrods GO90QA is the alternative I would consider for a compatible 2011–2022 4WD truck when you want a similarly comprehensive component package.
The ReadyLIFT 66-2725 is the simpler option when the factory coils are being retained and track-bar correction will be evaluated or handled separately.
Before ordering, measure the truck’s existing rake and confirm the model year, 4WD configuration, pickup or cab-and-chassis body, rear block, front axle arrangement, and factory options. Decide how much rake you want to preserve for towing rather than leveling the truck purely by appearance.
For a compatible F-450 where a full 2.5-inch front correction suits the intended wheel, tire, and towing setup, I would start with the ReadyLIFT 66-2726 and follow installation with a complete F-450-specific alignment.
