Finding the best struts for trucks starts with identifying what the strut actually needs to lift. A camper-shell window, toolbox lid, heavy tonneau cover, and front suspension all require different lengths, force ratings, fittings, and installation methods.
My first choice is IAQWE C16-15208 14269 16inch 45lb Truck Cap Camper Shell Gas Struts. Its 15.67-inch extended length, 9.37-inch compressed length, and sealed steel gas cylinder make it a practical replacement for worn camper-shell window supports.
My second choice is Truck Upfitters 2 Pcs Gas Struts 20 Inch. Each strut supplies 100 pounds of pressure, but careful center-to-center measurement is essential because these supports do not fit every ARE or SnugLid cover.
My third choice is BOXI 2pcs 10 Inch Gas Struts. BOXI 2pcs 10 Inch Gas Struts 35lb/156 N earns my third position for truck toolbox lids and other compact hatches. The pair is sized for a 26- to 39-pound lid, uses common replacement references such as 4058, and works across several toolbox brands, although brackets and screws are not included.
This guide compares all five choices by application, dimensions, support force, fitment, installation, and ownership concerns. It also explains how to measure an existing support, choose the right pressure, avoid installation mistakes, and distinguish lift supports from true front suspension struts.
Best Struts for Trucks
I selected these products for their relevance to common truck applications, the amount of useful fitment information supplied, and available customer-feedback evidence. The list also includes several brands and distinct use cases so a reader can match the part to a truck cap, tonneau cover, toolbox, heavy hatch, or Ram 1500 suspension rather than treating every strut as interchangeable.

IAQWE C16-15208 14269 16inch 45lb Truck Cap Camper Shell Gas Struts
For a worn camper-shell rear or side window, the IAQWE C16-15208 is the most broadly useful option in this group. It provides 45 pounds of support and measures 15.67 inches extended and 9.37 inches compressed. Those dimensions matter because a support can have the right general appearance yet fail to open the window fully, hold it securely, or close without overloading the hinges.
Its listed replacement references include ARE 14269, ARE14269, C16-22331, and C16-23993. That gives buyers several ways to compare the old part with the replacement before ordering. The stated compatibility also reaches beyond one camper-shell brand, covering many truck-cap rear and side windows, pickup toppers, RV storage doors, and Weather Guard toolbox lids.
The sealed nitrogen cylinder and high-grade steel construction are sensible for an exterior truck part exposed to rain, snow, road spray, and temperature changes. Installation is intended to require no drilling or complicated modification, which is helpful for a quick DIY repair. Still, “universal” should not replace measurement: mounting-ball style, attachment angle, and actual closed and open lengths remain important.
Pros
- Broad truck-cap and camper-shell application range.
- Useful 45-pound support force for many window and hatch lids.
- Multiple replacement numbers make cross-checking easier.
- No-drill installation is suitable for many DIY repairs.
Cons
- Not automatically compatible with every truck cap.
- Exact mounting geometry still needs to be verified.
My Opinion
This is the strongest general-purpose pick for a truck-cap window because it balances fitment information, moderate lifting force, weather-oriented construction, and easy installation. I would choose it first when the original support resembles the listed ARE or C16 references and the dimensions match.
Truck Upfitters 2 Pcs Gas Struts 20 Inch
Truck Upfitters targets a much heavier-duty job than the IAQWE pair. These two 20-inch supports provide 100 pounds of pressure each, making them suitable for certain ARE fiberglass tonneau covers, particularly LT, LSII, and LSX models. Four ball mounts are included, which can simplify replacement when the existing hardware is worn or when the cover uses that mounting arrangement.
The major strength here is also the biggest warning: pressure and length must be confirmed before purchase. The supplied measurements are taken from the center of one ball mount to the center of the other, not from the outer ends of the strut. Measuring the old part end to end can therefore lead to an incorrect order.
These are not guaranteed to fit all ARE covers, and the listing specifically warns that they are not compatible with every SnugLid tonneau cover. A buyer should measure the support fully open and fully closed, identify the cover model, and compare the ball-socket arrangement. The high force can be helpful on a large fiberglass lid but excessive pressure can make closing difficult or stress mounting points if the application is wrong.
Pros
- High 100-pound pressure per support for heavy fiberglass covers.
- Four ball mounts are included.
- Application information identifies several ARE cover families.
- Two-piece set replaces both sides together.
Cons
- Does not fit every ARE or SnugLid tonneau cover.
- Incorrect measurement can result in a poor fit or excessive force.
- Higher pressure is unnecessary for lighter lids.
My Opinion
This is the right second choice for a verified heavy fiberglass tonneau-cover application, not a universal truck-bed upgrade. Its pressure is impressive, but the buyer must treat the center-to-center measurement and exact cover model as mandatory checks.
BOXI 2pcs 10 Inch Gas Struts
BOXI is aimed at smaller lids, especially truck toolboxes. Each 10-inch support produces 35 pounds, and the pair is considered most suitable for a combined lid weight between 26 and 39 pounds. That range is more useful than simply seeing a pressure number because two supports share the lifting job, while the lid’s hinges, mounting position, and balance also affect how the system behaves.
The center-to-center dimensions are 10 inches extended and 6.6 inches compressed. Buyers should compare those measurements with the old supports and make sure the struts will not bottom out before the lid reaches its intended closed position. The long list of interchange references, including 4058, 8195695, SL10-35, and ML10-35, can help when replacing a factory support.
Compatibility extends to Weather Guard, Husky, Better Built, Delta, and UWS toolboxes, along with boat hatches, toy boxes, and cabinet doors. The package contains only two gas springs, however; screws, brackets, and other mounting hardware are not included. That is an important setup detail if the original brackets are damaged or missing. The compact size and moderate force make this a better toolbox choice than a long, high-pressure tonneau support.
Pros
- Compact 10-inch dimensions suit many toolbox lids.
- 35-pound rating per shock fits a stated 26- to 39-pound pair load.
- Broad interchange-number and toolbox-brand coverage.
- Two supports are included in one set.
Cons
- Mounting screws and brackets are not included.
- Not suitable for heavy lids outside the stated weight range.
- Exact mounting points still determine whether the dimensions work.
My Opinion
BOXI is a sensible compact-lid replacement when the toolbox measurements and weight fall within its range. I would select it over a stronger support for a normal truck toolbox because excessive force can make a small lid awkward to close and may burden the hardware.
ARANA 28 Inch 100LB Gas Struts
ARANA is built for large, heavy lids rather than small windows or toolboxes. Each 28-inch support is rated at 100 pounds, and the recommended lid range is 85 to 115 pounds with a side length of at least 37 inches. That application guidance helps narrow the choice to substantial tonneau covers, camper-shell toppers, floor hatches, trap doors, and similar builds.
The listed center-to-center length is 27.95 inches extended and 16.5 inches compressed. These numbers should be compared with the actual mounting points, not just the overall lid width. A long support needs enough room to operate through its full travel, and the side-length guidance suggests that this model is intended for a broad lid with mounting geometry that can accommodate its reach.
Construction combines carbon steel with PA66 ball ends, and the product information states that the supports went through more than 20,000 endurance tests. That claim indicates an effort toward durability, but it should not be interpreted as proof that every installation will last equally long. ARANA also warns that the supports are very strong and may only compress after successful installation. Extra care is appropriate during fitting, and the supplied 365-day replacement support is useful if an unfit issue occurs.
Pros
- Designed for heavy lids weighing 85 to 115 pounds.
- Long travel suits large covers and hatches.
- Carbon steel construction with PA66 ball ends.
- Two supports are supplied as a pair.
Cons
- Too strong and too long for many ordinary truck lids.
- Installation can be difficult because the supports resist compression.
- Requires at least 37 inches of side length according to the application guidance.
My Opinion
ARANA is the best fit among these choices for a genuinely heavy, wide lid that meets its dimensional requirements. It ranks below the more broadly useful options because its strength and length make accurate measuring especially important, and a mismatch can create installation and closing problems.
Rough Country N3 Leveling Struts
Rough Country N3 Leveling Struts belong to a different category from the gas lift supports above. They are preloaded front suspension struts for a specific Ram 1500 application, intended to add a 2.5-inch front lift and level the truck’s stance. The assembly arrives with the coil spring installed, so the owner does not need to disassemble a strut or compress a spring during installation.
The suspension-focused design uses a 1 3/8-inch bore, nitrogen charging, application-specific valving, low-friction shock oil, and a leak-proof piston seal. In practical terms, those details are aimed at damping control and a stable ride over changing surfaces rather than holding open a hatch. The stated infinitely variable damping is intended to adapt to road conditions, while the bolt-on format can reduce installation complexity compared with building a strut from separate components.
Fitment is narrow and must be treated as a hard requirement. It covers Ram 1500 4WD trucks from 2012 through 2018 and the Ram 1500 Classic, but excludes 3.6L V6 models, Warlock models, and trucks with four-corner air suspension. It also cannot be used with strut spacers. This is therefore a truck suspension choice, not a substitute for a gas spring on a cap, toolbox, or tonneau cover.
Pros
- Preloaded, fully assembled strut simplifies bolt-on installation.
- Provides a stated 2.5-inch front lift and leveling effect.
- Application-specific damping is intended for varied terrain.
- Fits a defined range of Ram 1500 4WD applications.
Cons
- Excludes several Ram configurations and all four-corner air suspension models.
- Not compatible with strut spacers.
- Does not serve truck-cap or toolbox lift-support applications.
My Opinion
Rough Country is a worthwhile pick only for the specified Ram 1500 suspension application. It is included because truck owners often use “struts” to mean suspension components, but its fitment limitations make verification more important than its strong hardware specifications.
How I Selected These Best Struts for Trucks
The products were organized by practical relevance rather than by one universal specification. Gas supports were compared for length, compressed travel, pressure, intended lid weight, replacement references, mounting hardware, and application range. The Rough Country option was assessed separately because it is a front suspension leveling assembly with vehicle-specific fitment.
Measure the existing support from the correct reference points before ordering. For ball-mounted gas springs, center-to-center length is often more useful than the total end-to-end measurement.
Customer feedback volume and ratings were considered where supplied, but those figures do not override fitment information. A highly rated support can still be wrong for a particular lid if its force, length, or mounting angle does not match. Brand diversity was also useful because IAQWE, Truck Upfitters, BOXI, ARANA, and Rough Country address different truck-owner needs.
Do not compare a toolbox lift support directly with a suspension strut. Both may use gas pressure, but their jobs, attachment points, load paths, and safety requirements are entirely different.
How to Choose the Best Struts for Trucks
The best struts for trucks are selected by application first, then by dimensions and force. Start by deciding whether the part supports a lid or changes suspension height. After that, verify the old part’s extended and compressed lengths, mounting ends, pressure rating, and the weight or vehicle configuration it must handle.
- Match the part to the exact lid, cover, toolbox, hatch, or truck suspension.
- Measure center to center when the strut uses ball sockets.
- Choose enough pressure to support the load without making closing difficult.
- Confirm compressed length and mounting angle before installation.
- Check vehicle exclusions when buying a suspension strut.
Measure Both Open and Closed Lengths
Remove guesswork by measuring the existing support fully extended and, if possible, fully compressed. For ball-mounted supports, place the tape or ruler at the center of each ball socket. Record the measurement in inches and compare it with the replacement data. A support that is only slightly too long can prevent a lid from closing, while one that is too short may limit opening travel.
Estimate the Lid Weight and Balance
Gas strut pressure is not the same as the total weight of the lid. Hinge location, mounting distance from the hinge, lid width, and the use of one or two supports all change the force required. A pair rated for a 26- to 39-pound toolbox lid should not automatically be used on a much heavier cover. Likewise, installing very strong supports on a light lid can make the lid spring upward or place stress on brackets.
Inspect the Mounting Ends
Check whether the old part uses ball sockets, studs, eyelets, or another fitting. Also inspect the brackets attached to the lid and body. A replacement may have the correct length and force but still fail to install if the ends do not match. BOXI, for example, supplies two gas springs but no screws or brackets, so the original hardware must be reusable or sourced separately.
Separate Lift Supports from Suspension Components
A gas spring holds a panel or lid open. A suspension strut controls wheel movement and carries suspension loads. Never substitute one category for the other. The Rough Country assembly is made for specific Ram 1500 front suspension applications, while the other four products are lift supports for lids and windows.
Installation and First-Use Tips
Most lift-support replacements are manageable for a careful DIY owner, but the lid should be supported before removing the old parts. A hatch or tonneau cover can fall suddenly once its supports are disconnected. Use a prop that cannot slip, keep fingers away from hinge and socket pinch points, and replace both sides when the application uses a matched pair.
Compare the new support with the old one before attaching anything. Confirm the extended length, mounting orientation, end fittings, and approximate force. Many ball-socket supports can be pressed onto the existing studs after the retaining clip is moved, but the exact attachment method varies. Do not drill new holes simply to force a poor fit unless the application specifically allows modified mounting.
After installation, open the lid slowly and watch for binding. Check that the support does not rub against the window, cover, hinge, or surrounding sheet metal. Close the lid gently several times before normal use. A proper installation should allow the lid to move through its intended range without sudden stops or excessive side loading.
Safety When Handling Strong Gas Struts
Large supports such as the ARANA and Truck Upfitters models can exert substantial force. Do not try to shorten, puncture, heat, bend, or disassemble a gas spring. If a support is too long or too strong, order the correct part rather than attempting to alter it.
- Support the lid mechanically before removing either old strut.
- Wear eye protection while releasing clips or working near pressurized parts.
- Keep hands clear of ball sockets and closing hinges.
- Never install only one support when the design calls for a pair.
- Stop if the mounting bracket flexes, cracks, or pulls away from the panel.
How to Make Lift Supports Last Longer
Keep the polished piston rod clean and avoid scraping it with tools. Dirt or corrosion on the rod can damage the seal as the support cycles. Do not apply thick grease to the exposed rod unless the manufacturer specifically calls for it; grease can collect grit and may not help the gas seal.
Inspect the supports periodically for oil leakage, dents, rust, bent rods, loose sockets, or cracked brackets. A weak support may allow a lid to drift downward or fail to remain open. Replace worn supports as a pair when practical so both sides provide similar assistance. Exterior truck parts face water, salt, dust, and temperature changes, so regular visual checks are especially worthwhile.
Cold Weather and Storage Considerations
Gas supports can feel weaker in cold conditions because gas pressure changes with temperature. A lid that stays open during warm weather may require extra care in winter. Do not rely on a marginal support to hold a heavy cover above your head in freezing conditions; use a secondary prop when loading or servicing the truck.
If a truck or camper shell is stored for a long period, leave the supports in their normal installed position rather than forcing them into an unusual angle. Keep the rod surfaces clean, and avoid placing heavy objects against a lid that the struts were not designed to support. Storage stress can damage brackets even when the gas springs themselves remain intact.
Common Mistakes When Replacing Truck Struts
Most ordering and installation problems come from treating struts as universal parts. The appearance of two supports may be similar while their travel, pressure, or end fittings differ substantially.
- Ordering by vehicle year alone without identifying the lid or cover model.
- Measuring from the outer ends instead of socket center to socket center.
- Ignoring compressed length and checking only the open length.
- Choosing a higher pressure rating without considering hinge and bracket stress.
- Reusing cracked mounting brackets because the new struts appear to fit.
- Installing a suspension leveling strut on a vehicle configuration it excludes.
- Forcing a strong gas spring into position without a secure lid prop.
When Should Truck Struts Be Replaced?
Replacement is appropriate when a lid no longer stays open, drops unexpectedly, opens only partway, or requires noticeably more manual assistance. Visible oil around the rod, a dented cylinder, bent hardware, or loose ball sockets are also warning signs. On a pair-mounted application, replacing only the visibly weaker side can leave the lid unevenly supported.
There is no single replacement interval supplied for these products. Actual life depends on cycling frequency, weather exposure, lid weight, installation angle, and the condition of the mounting brackets. A support used daily on an outdoor truck may wear differently from one used occasionally on a stored camper shell.
FAQS About Best Struts for Trucks
What are the best struts for a truck camper shell window?
The IAQWE C16-15208 is the strongest general pick in this list for a camper-shell window. It provides 45 pounds of support, fits several listed ARE and C16 replacement references, and offers dimensions suited to many truck-cap rear or side windows. Confirm the original measurements and mounting ends first.
How do I measure truck lift supports correctly?
Measure from the center of one mounting point to the center of the other, especially when the support uses ball sockets. Record both the fully extended and fully compressed lengths. Also identify the fitting style, lid weight, and mounting angle.
Are stronger gas struts always better for a truck lid?
No. Excessive pressure can make a lid difficult to close and may stress hinges, brackets, or the lid panel. Choose a force rating that matches the lid weight and mounting geometry rather than automatically choosing the highest available rating.
Which struts fit a truck toolbox?
The BOXI 10-inch, 35-pound gas struts are intended for many truck toolbox applications, including Weather Guard, Husky, Better Built, Delta, and UWS boxes. The pair is most suitable for a combined lid weight of about 26 to 39 pounds, and the package does not include screws or brackets.
Do truck tonneau-cover struts fit every cover?
No. Tonneau-cover supports are highly dependent on cover model, length, pressure, and mounting points. Truck Upfitters specifically warns that its 20-inch, 100-pound supports do not fit all ARE or SnugLid covers, so center-to-center measurements and model identification are necessary.
Are Rough Country N3 struts lift supports for truck caps?
No. Rough Country N3 Leveling Struts are preloaded front suspension components for specified Ram 1500 4WD trucks. They are not gas supports for lids, windows, toolboxes, or tonneau covers.
Final Thoughts
For most camper-shell window replacements, IAQWE is the best struts for trucks choice in this group because its dimensions, 45-pound force, and compatibility information are well balanced. Truck Upfitters is the better option for a verified heavy ARE fiberglass cover, while BOXI is the practical toolbox pick. ARANA suits large heavy lids, and Rough Country belongs on the shortlist only for its specified Ram 1500 suspension application.
