Finding the best strut and coil spring assembly is less about choosing the cheapest listing and more about matching the assembly to the exact vehicle, suspension position, and repair goal. A complete unit can simplify installation, but a fitment mistake can leave you with the wrong spring rate, mounting position, or set of parts.
My first choice is Monroe Shocks & Struts Monroe Shocks Struts Monroe 171572L Suspension. Its preassembled mount, coil spring, and strut eliminate the need for a spring compressor while helping restore ride height and normal load support.
My second choice is Auto Shack Autoshack Front Rear Complete Struts Assembly Springs. The 4-piece kit includes front and rear complete assemblies with mounts, boots, bumpers, spring seats, and isolators, although careful vehicle and position verification remains essential.
My third choice is KUIPERAUTO 1333376L 1333376R Complete Rear Struts Coil Spring Assembly. KUIPERAUTO 1333376L 1333376R Complete Rear Struts Coil Spring Assembly takes third place as a rear-pair solution for selected Toyota Camry applications. It arrives with the major spring and mounting components together, includes an installation manual, and is aimed at owners who want a more straightforward rear suspension replacement rather than a full-vehicle kit.
This guide compares all five choices, explains where each one fits, and covers the checks that matter before ordering. You will also find practical advice about identifying worn suspension parts, preparing for installation, avoiding fitment errors, checking ride height afterward, and getting longer service from a replacement assembly.
Best Strut and Coil Spring Assembly
I selected these products for their relevance to complete strut-and-spring replacement, the amount of useful fitment and component information supplied, customer-feedback evidence when available, and variety across vehicle applications. The ranking is not a substitute for checking the vehicle’s year, drivetrain, engine, trim, suspension position, and qualifying notes before purchase.

Monroe Shocks & Struts Monroe Shocks Struts Monroe 171572L Suspension
Monroe’s 171572L is a strong choice for owners of specified Chrysler Town & Country, Chrysler Voyager, Dodge Caravan, and Dodge Grand Caravan models. The application list covers 2001–2007 Town & Country, 2001–2003 Voyager, and 2001–2007 Caravan and Grand Caravan, but the correct side and exact vehicle details still need confirmation before ordering.
The biggest convenience is that the upper mount, coil spring, and strut arrive as one assembled unit. That removes the need to transfer the old spring and compress it during installation, a step that can add time and introduce a serious safety hazard for inexperienced home mechanics. A vehicle-specific spring and mount also give the buyer a better chance of retaining the intended ride height and suspension geometry than a poorly matched universal combination.
Monroe states that the assembly uses high-quality steel and an improved tube and weld design for structural integrity. Its OE-style configuration is intended to support predictable fit and handling, while the calibrated spring is intended to carry the vehicle’s weight without leaving the front end sitting too low. The trade-off is that this is an application-specific part, not a flexible solution for unrelated vehicles or custom suspension changes.
Pros
- Fully assembled design avoids spring-compressor work.
- Application-specific spring, mount, and strut support normal ride height.
- Broad fitment across listed Chrysler and Dodge minivans.
- Steel construction is intended for durable structural performance.
Cons
- Fitment must be confirmed by year, engine, trim, and qualifier notes.
- The supplied information identifies a specific assembly rather than a complete four-corner kit.
My Opinion
This is the best-balanced pick in the group when it matches the vehicle. Its complete, vehicle-specific construction makes it especially appealing for a direct replacement where safety, correct ride height, and reduced installation complexity matter more than customization.
Auto Shack Autoshack Front Rear Complete Struts Assembly Springs
AutoShack’s 4-piece package is aimed at a much more specific group: owners of the Toyota Camry from 1997–2001 with front-wheel drive and either the 2.2-liter four-cylinder or 3.0-liter V6, plus Toyota Avalon models from 1997–2003 with front-wheel drive and the 3.0-liter V6. It is a front-and-rear replacement package, so it can make sense when several assemblies are worn at the same time.
Each complete unit brings together the strut, coil spring, mount, boot, bumper, spring seat, and isolator. That approach reduces the number of old parts that must be reused and can make the repair more consistent across the axle positions. The supplied extended and compressed lengths also give a buyer useful dimensional information, but those figures should be compared only with the correct vehicle application and position rather than used as a general sizing shortcut.
The assembly is described as corrosion-resistant and intended to preserve ride control, alignment stability, and long-term ride quality. A four-piece package may be more economical in labor when both axles need attention, but it is unnecessary expense if only one corner is damaged and the other assemblies remain sound. The listing also emphasizes confirming position, side, and fitment, which is particularly important because front and rear units are not interchangeable.
Pros
- Includes four complete assemblies for front and rear replacement.
- Each unit includes major mounting and protective components.
- Preassembled construction can reduce installation time.
- Useful listed length measurements for application comparison.
Cons
- Fitment is limited to specific Camry and Avalon configurations.
- A full set may be more than needed for a single-corner repair.
- Front, rear, and side details must be checked before ordering.
My Opinion
This is the sensible second choice for a correctly matched Toyota that needs a broad suspension refresh. Its main advantage is completeness, while its main limitation is the narrow application range and the possibility of buying more assemblies than the repair actually requires.
KUIPERAUTO 1333376L 1333376R Complete Rear Struts Coil Spring Assembly
KUIPERAUTO supplies a left-and-right rear pair with the spring, strut, mount, boot, jounce bumper, upper spring seat, and lower spring isolator already combined. That makes it a focused option for repairing both rear corners at once, rather than a partial single-side replacement that leaves the opposite side with a different age and condition.
The supplied replacement numbers include 1333376L, 1333376R, 172942, and 172943. The listing information contains an important fitment inconsistency: the source title mentions a 2012–2017 Toyota Camry SE rear application, while the application note says “Only LE XLE.” Because of that conflict, buyers should not rely on the title alone. The vehicle fitment tool, original part information, and exact trim should all be checked before payment.
The complete design is intended to reduce installation steps, and an installation manual is included. The high-quality steel construction and oil-hydraulic system are presented as ways to reduce vibration and road bumps while supporting a more stable, comfortable ride. Still, this is a rear-pair product, not a complete front-and-rear suspension solution, and it is not a substitute for diagnosing worn control-arm bushings, links, or other rear hardware.
Pros
- Includes matched left and right rear assemblies.
- Spring, mount, isolators, boot, and jounce bumper are included.
- Installation manual is supplied.
- Hydraulic damping and spring construction target smoother rear control.
Cons
- Application wording conflicts between the title and fitment note.
- Only the rear pair is included.
- Exact Camry trim and vehicle compatibility require extra verification.
My Opinion
This is a useful targeted option when both rear Camry assemblies need replacement, but the fitment contradiction keeps it below the first two choices. I would treat compatibility confirmation as mandatory rather than optional for this product.
MOSTPLUS Front Rear Complete Strut Coil Spring Assembly 11605 11606 172497R 172497L
MOSTPLUS offers a complete set of four assemblies for the 2007–2011 Honda CR-V. For an owner dealing with worn suspension at both axles, the package has an obvious practical advantage: front and rear replacements can be planned together instead of mixing old and new assemblies across the vehicle.
The listed interchange numbers include 11605, 11606, 172497R, 172497L, 15085, 15086, and several related numbers. Those references can help compare the listing with existing parts information, but they do not replace vehicle verification. A CR-V’s year and trim should be entered into the fitment tool, and the buyer should confirm which part is assigned to each side and axle before opening the package.
MOSTPLUS describes the parts as made from high-quality materials with anti-corrosion and anti-oxidation properties. The listed piston rod is intended to rebound automatically, while the steel spring is intended to improve ride comfort, reduce high-frequency vibration, and limit impact noise. These are useful goals for a daily-driven crossover, although no supplied information establishes a particular service life or guarantees that every suspension noise will disappear after installation.
Pros
- Four-piece set covers front and rear positions.
- Designed specifically for 2007–2011 Honda CR-V applications.
- Anti-corrosion and anti-oxidation claims support outdoor durability.
- Includes numerous replacement-number references for comparison.
Cons
- Fitment must be confirmed for the exact CR-V configuration.
- The supplied information does not provide a customer-feedback count.
- A four-piece set may exceed the needs of a one-axle repair.
My Opinion
MOSTPLUS earns its place as a practical full-set alternative for the specified CR-V years. It is most attractive when several assemblies need replacement, but buyers should confirm the vehicle details and avoid interpreting the comfort claims as a guarantee against unrelated suspension problems.
Generic Pair Rear Shock Absorber Struts Coil Spring Assembly
This Generic pair is intended for the rear left and rear right positions on a Tesla S from 2012–2016. The package contains a coil spring, shock, and strut, using a single-pipe design. For an owner seeking a matched rear pair rather than a lone replacement, that left-and-right coverage is the central benefit.
The listing provides a long set of interchange numbers, including 1015620-03-D, 1015620-01-E, 1015620-00-E, 1015620-00-A, and multiple related revisions. Those references may help identify the correct original assembly, but the number list should be compared carefully with the vehicle’s existing part and exact production details. The supplied data does not provide a customer rating or customer-feedback count, so there is less public evidence here than for the other ranked choices.
This option is limited to the rear axle and should not be mistaken for a complete Tesla suspension kit. The generic branding also makes careful inspection of packaging, connectors or mounting details, and part-number correspondence particularly important before installation. If the vehicle has additional air-suspension, electronic, or chassis-specific equipment around the assembly, the buyer should confirm that the replacement is appropriate before removing the original parts.
Pros
- Matched pair covers both rear sides.
- Clearly identifies rear left and rear right mounting positions.
- Includes the coil spring, shock, and strut together.
- Provides numerous interchange numbers for fitment comparison.
Cons
- Generic branding provides less product-specific context.
- No rating or customer-feedback count is supplied.
- Only the rear pair is included.
- Exact Tesla part-number compatibility is especially important.
My Opinion
This is a narrowly targeted option for a Tesla S owner who can verify the original number and rear application. It ranks fifth because the supplied information offers less evidence and fewer ownership details, not because a rear pair is inherently unsuitable.
How I Selected These Best Strut and Coil Spring Assembly Options
The selection emphasized complete assemblies rather than bare dampers or loose springs. A useful complete unit should identify its intended vehicle, axle or side position, included components, and installation advantages clearly enough for a buyer to make a responsible comparison. I also considered available customer-feedback signals: Monroe lists a 4.2 rating from 359 customers, AutoShack lists 4.4 from 263, KUIPERAUTO lists 4.4 from 143, and MOSTPLUS lists 4.6 from 33. No rating or count was supplied for the Generic Tesla listing, so that absence affects confidence and ranking.
Brand diversity also matters because a single manufacturer rarely covers every vehicle application. These choices span Chrysler and Dodge minivans, Toyota passenger cars, a Honda crossover, and a Tesla application. That makes the comparison useful without pretending that one assembly can fit every vehicle.
Fitment is the deciding factor, not the position in this ranking. A highly rated assembly is still the wrong purchase if the year, trim, drivetrain, axle, side, or original part number does not match.
I gave extra weight to preassembled construction because it reduces spring-transfer work. That convenience matters most for first-time installers, but it does not remove the need for safe lifting, correct torque procedures, and a post-installation alignment check when required.
How to Choose a Strut and Coil Spring Assembly
Start with the vehicle rather than the product name. Enter the complete year, make, model, engine, drivetrain, trim, and position into the seller’s fitment tool, then compare the result with the original assembly and the repair estimate. The right choice should match both the vehicle and the scope of work.
- Confirm the exact vehicle configuration and fitment notes.
- Identify whether the part is front, rear, left, right, or a matched pair.
- Check whether the package covers one corner, one axle, or all four positions.
- Prefer complete assemblies when avoiding spring-compressor work is important.
- Compare included mounts, isolators, boots, bumpers, and spring seats.
Confirm the application before comparing brands
Vehicle names alone are not precise enough. A product may fit one engine, drivetrain, body style, or trim but not another version sold in the same model year. The AutoShack package, for example, specifies front-wheel-drive Camry and Avalon applications, while the KUIPERAUTO listing contains conflicting trim language. Those details are not minor; they can determine whether the spring rate, mounting points, and assembly dimensions are correct.
Use the seller’s confirmation tool, but treat it as one part of the process. Compare the original part number, look at the old assembly’s mounting arrangement, and call a parts professional when the listing produces a qualifier or contradiction. Save a screenshot of the confirmed application and keep the order information until the parts have been physically compared.
Decide how much of the suspension to replace
A single damaged assembly does not automatically require four replacements. If one spring is broken or one damper is leaking, replacing both sides on the same axle is often a more balanced repair because the left and right sides then have similar age and damping characteristics. A complete four-piece package becomes more appealing when the vehicle has high mileage, multiple worn assemblies, or a history of uneven ride control.
Do not replace a healthy front pair simply because a rear pair is needed. At the same time, inspect all four corners while the vehicle is on a lift or safely supported. Worn mounts, cracked springs, leaking dampers, damaged boots, and uneven ride height can appear together, especially on vehicles that have spent years carrying heavy loads or driving over rough roads.
Complete Assembly Versus Separate Suspension Parts
A complete assembly arrives with the primary strut and spring already combined, often along with the mount, seat, isolator, boot, and bumper. This can reduce labor and eliminates the need to disassemble the old spring from the strut. For a beginner, that is a meaningful safety and convenience advantage because compressed coil springs store substantial energy.
Separate parts may offer more control for an experienced mechanic. Someone restoring a vehicle, changing spring rates, or selecting a premium damper may want to choose every component individually. That route can also make sense if the existing spring and mount are in excellent condition. The disadvantage is that labor increases, compatibility becomes a multi-part calculation, and a spring compressor or professional installation may be necessary.
There is also a condition issue. A replacement damper paired with an old mount or tired isolator may leave noise or looseness behind. A complete assembly reduces that uncertainty by replacing more of the wear-related hardware at once, although it does not repair control arms, ball joints, sway-bar links, wheel bearings, or chassis damage.
When a Strut and Spring Assembly Needs Replacement
Common warning signs include a leaking damper, repeated bouncing after a bump, excessive nose dive during braking, unusual body roll, uneven ride height, clunking near the upper mount, or a spring that is cracked or broken. Tire cupping and irregular wear can also point to poor damping or alignment problems, although tires and wheel balance should be checked separately.
A vehicle that pulls, wanders, or sits unevenly deserves a broader inspection. Those symptoms may involve alignment, tire pressure, steering parts, worn bushings, or a bent component rather than the strut assembly alone. Replacing the assembly without identifying the underlying cause can produce an expensive but incomplete repair.
Look for fluid around the damper body, but do not assume every damp surface proves failure. A qualified inspection can distinguish normal residue from a meaningful leak. Springs should be checked for broken coils, corrosion loss, and uneven seating. Mounts should be checked for torn rubber, excessive movement, or bearing noise where applicable.
Installation and Setup Basics
Preassembled units simplify the mechanical work, but suspension replacement is still a safety-critical task. Use a level work area, engage the parking brake, chock the wheels, and support the vehicle with properly rated jack stands. Never rely on a jack alone while working underneath the vehicle.
Before removing anything, compare the new assembly with the original. Check overall length, mounting holes, spring orientation, connector or bracket locations, and left-versus-right markings. Photograph the old installation if the orientation is not obvious. Keep fasteners organized because similar-looking bolts may have different lengths or positions.
Follow the vehicle service procedure for loosening and tightening fasteners. Some suspension fasteners must be tightened with the vehicle at normal ride height or with the suspension loaded. Avoid using an impact tool to final-tighten every fastener unless the vehicle procedure specifically permits it. Correct torque is important for preventing looseness, bushing preload, and premature wear.
After installation, confirm that the spring is seated correctly, the mount is oriented properly, and brake hoses or sensor wires are routed away from moving parts. Reinstall the wheel, lower the vehicle safely, and check for obvious noise or interference before driving. A short, slow test drive should be followed by another visual inspection.
Alignment After Installation
Changing a strut assembly can affect wheel position, especially when the assembly connects to the steering knuckle. Even when the replacement is intended to match the original dimensions, an alignment check is prudent. It can identify toe, camber, or caster changes that may quickly damage tires or cause the vehicle to pull.
Alignment is especially important after replacing front assemblies, after correcting a visibly uneven ride height, or after finding irregular tire wear. Ask the shop to inspect steering and suspension joints at the same time. An alignment cannot compensate for a loose ball joint, bent knuckle, worn control-arm bushing, or damaged wheel bearing.
Record the alignment readings if possible. Keeping before-and-after information can help identify whether the vehicle needs additional parts and gives you a useful baseline for future tire-wear checks.
How to Make a Replacement Assembly Last Longer
Driving style and road conditions have a major effect on suspension life. Slow down for potholes, speed bumps, and rough transitions instead of striking them at speed. Avoid carrying loads beyond the vehicle’s limits, since excessive weight increases spring compression and places more demand on damping components.
Keep tire pressure at the vehicle manufacturer’s recommended setting. An underinflated tire transfers more impact into the suspension, while an overinflated tire can reduce compliance and change handling. Rotate tires according to the vehicle schedule and address alignment problems before irregular wear becomes severe.
During routine service, look for corrosion, damaged boots, loose fasteners, leaking dampers, and broken spring coils. Clean heavy road salt and mud from exposed components when practical, but do not direct high-pressure water at seals, electrical connectors, or sensitive areas. If a new noise appears after installation, investigate it promptly rather than waiting for the sound to become severe.
Common Mistakes to Avoid
Most suspension-purchase problems come from assumptions: assuming the model name is enough, assuming left and right parts are identical, or assuming a complete assembly fixes every source of noise. A few minutes of verification can prevent an incorrect order and a second installation.
- Do not order by year and model alone when engine, trim, drivetrain, or position matters.
- Do not confuse a rear pair with a complete front-and-rear kit.
- Do not use a spring compressor casually if the assembly is not preassembled.
- Do not reuse visibly damaged mounts, isolators, boots, or fasteners without checking the service procedure.
- Do not skip an alignment check after front suspension work.
- Do not assume a clunk comes from the strut when links, bushings, or bearings may be worn.
Stop and verify any listing that contains conflicting application language. The KUIPERAUTO title and application note illustrate why the exact trim and vehicle-confirmation result should be checked before installation.
What to Check When the New Assembly Does Not Feel Right
A slightly different feel immediately after installation can come from new damping, changed ride height, tire pressure, or the vehicle adapting to a corrected suspension position. However, loud clunks, spring noise, steering pull, scraping, or a visibly tilted vehicle should not be dismissed.
First, inspect the spring seating, upper mount orientation, wheel fasteners, and all visible brackets. Confirm that no brake hose, ABS wire, or liner is contacting the tire or spring. Next, verify that the correct side and axle assembly were installed. If the problem remains, stop driving aggressively and have the suspension inspected.
Noise that remains after a complete assembly replacement may originate elsewhere. Sway-bar links, control-arm bushings, ball joints, tie-rod ends, wheel bearings, and exhaust shields can all create sounds that seem to come from the strut area. A systematic inspection is more useful than repeatedly replacing parts based only on sound location.
Pair Replacement and Ride-Height Matching
Replacing both sides of an axle is often preferable when the assemblies have similar age and wear. A matched pair helps keep damping and spring support more consistent from left to right. This is why the KUIPERAUTO rear pair and the Tesla rear pair may be more appropriate than purchasing one side alone when both sides are tired.
Ride height should be measured on level ground with comparable fuel and cargo conditions. Measure from the wheel center to the fender opening, or use the vehicle manufacturer’s specified method. Compare left and right sides after the vehicle has settled. A small difference may come from load distribution or measurement variation, while a significant difference can indicate an incorrect spring, poor seating, bent hardware, or another suspension issue.
Do not use a new spring to compensate for a vehicle that is overloaded or damaged. If one side remains low after installation, identify the cause before adding spacers or making modifications that were not part of the original design.
Safety and Ownership Tips for First-Time Buyers
Read the complete listing before ordering, including notes hidden behind a fitment-information icon. Keep the original parts until the new assembly has been checked against them. If the package arrives with a bent rod, damaged spring coating, crushed boot, missing hardware, or an unexpected side marking, photograph the condition and resolve the issue before installation.
Ask whether the seller supplies only the assemblies or also includes any special nuts, bolts, or installation instructions. The KUIPERAUTO listing specifically includes an installation manual, while the supplied information for the other products does not promise every possible fastener. Having the correct replacement hardware available can prevent delays during the repair.
If you are not comfortable supporting the vehicle or handling suspension fasteners, professional installation is the safer option. A preassembled product reduces one hazardous step, but it does not remove the risks associated with lifting the vehicle, separating suspension components, and tightening structural fasteners correctly.
FAQS About Best Strut and Coil Spring Assembly
Should I replace one strut and coil spring assembly or both sides?
When both sides on an axle have similar age or wear, replacing them as a pair usually gives more consistent damping and ride height. A single-side replacement may be reasonable after isolated damage, but the opposite side should be inspected carefully.
Are complete strut and coil spring assemblies easier to install?
Yes. A preassembled unit usually avoids transferring the old spring and compressing it with a spring compressor. You still need safe lifting equipment, correct fastener procedures, and a fitment check before installation.
Does every complete assembly fit every trim of a vehicle?
No. Engine, drivetrain, trim, body style, axle, and suspension package can change compatibility. Enter the full vehicle information into the fitment tool and investigate all qualifier notes.
Do I need an alignment after replacing a front assembly?
An alignment check is strongly advisable because front strut removal can affect wheel angles. It is particularly important when the vehicle pulls, the steering wheel is off-center, or the tires show uneven wear.
Can a new strut assembly fix all suspension noises?
No. Clunks and rattles can also come from sway-bar links, control-arm bushings, ball joints, bearings, mounts, or loose hardware. A complete assembly replaces several components, but it does not repair unrelated suspension parts.
What should I do if the product listing has conflicting fitment details?
Do not rely on the product title alone. Compare the original part number, confirm the exact trim and position, use the seller’s vehicle tool, and contact the seller or a parts professional before ordering.
Final Thoughts
The best strut and coil spring assembly is the one that matches the vehicle precisely and covers the repair you actually need. Monroe 171572L is my top choice for its application-specific, fully assembled design; AutoShack is the strongest broad four-corner alternative for the specified Toyota applications; and KUIPERAUTO is a useful third choice when its conflicting Camry fitment details are confirmed. MOSTPLUS and the Generic Tesla pair remain viable targeted options when their vehicle and position requirements are satisfied.
