When your vehicle's liftgate begins to sag, hesitate during ascent, or fail to stay open entirely, the culprit is almost certainly a fatigued gas spring. Suspa automotive replacement shock lift supports are engineered to restore the precise hydraulic pressure required to manage the heavy lifting of hatchbacks, trunks, and hoods. Unlike standard dampers, these specialized supports utilize pressurized nitrogen gas to provide a controlled, smooth motion that protects your vehicle's hinges and prevents accidental closure. Selecting the correct replacement is not merely about finding a part that fits. It is about matching the specific force requirements and mounting configurations of your vehicle to ensure long-term reliability and safety.

CHECK LENGTHS AND PRESSURE BEFORE ORDERING. THESE DO NOT FIT ALL TOPS! THE MEASUREMENTS ARE FROM CENTER OF BALL MOUNT TO CENTER OF BALL MOUNT, NOT FROM END TO END OF STRUT! SEE PICTURE! Use a measuring tape to measure the door gas strut that you are replacing. Measure from the CENTER of the gas prop head (little plastic end), to the other side. DO NOT measure camper struts from the end of the gas prop, your measurement will be too long. Note that most applications allow for 1-5% size variation.
Truck Upfitters Pair of 30 pound (each) gas struts. 13.0" extended length & 8.1" compressed length. This size of door shock absorber is for tall medium weight rear or side camper windows / camper shell doors. Each canopy shock has 30 lbs of pressure, for a total of 60 lbs of pressure. Please note that this does not mean that it can lift something that is 60 lbs. the typical hinged-style door weight for this prop is approximately 30-50 lbs, including the weight of the camper shell locks and keys.
These gas lift cylinders do not fit all camper shell brands / models. Measure your strut from center of socket to center of socket when fully opened & fully closed to get accurate measurement. Please see pictures to determine how to measure. Do NOT measure from end to end. Measurement must be from the center of plastic ball mount on each end of the gas spring lift. Measurement is important to ensure they open properly and get a good camper shell seal against the camper shell gasket when closed.
Comes with four 10mm ball mounts for alternate 'other than truck camper shell' applications, such as in camper / canopy windoors, RV doors and awnings, boat hatch spring lifts, gas struts for cabinets, storage bed lifts, toolbox struts, etc. These gas shock lift supports CANNOT be compressed by hand. These gas props MUST be installed in the EXTENDED / OPEN position. It is nearly impossible to install them in the CLOSED position. Please refer to the install video for guidance on how to install.
Equivalent to Suspa # c16-04464 or c16-04464A or Stabilus # 0516. These camper shell shocks are compatible with many truck canopy types, including LEER truck cap parts, ARE truck topper parts, Glasstite parts, Century parts, Snugtop replacement parts Astro tops, ATC campers, and many other fiberglass brands that utilize gas shocks / gas springs / gas lift cylinders. Compatible with many gas lift brands, including stabilus, lift o mat, and Suspa. These are OEM quality and perfect for your topper!
Most truck owners settle for heavy, sagging canopy doors that feel like a chore to operate, but these Truck Upfitters gas props restore that smooth, effortless lift. These 13-inch struts provide a combined 60 pounds of pressure, making them ideal for medium-weight rear or side windows on brands like Leer, ARE, or Snugtop. The installation requires precision. You must measure from the center of one ball mount to the center of the other to ensure a perfect seal against your gasket. I found it helpful that they include four extra 10mm ball mounts, which adds versatility for RV doors or even boat hatches. Just remember that these cannot be compressed by hand, so you'll need to install them while the door is in the fully extended position.

A Guide to Selecting the Best suspa automotive replacement shock lift supports
Understanding Pressure Ratings (Newton Force)
The most critical specification when shopping for lift supports is the force rating, typically measured in Newtons (N). Every vehicle manufacturer designs the liftgate with a specific weight load in mind, requiring a precise amount of pressure to counteract gravity. If you select a support with too little force, the hatch will fail to stay open or will drop unexpectedly. Conversely, if the Newton rating is too high, you risk overstressing the liftgate hinges or making the hatch difficult to close manually. Always cross-reference your vehicle's original equipment manufacturer (OEM) specifications to ensure the replacement supports provide the exact lifting capacity required for your specific trim and model year.
Stroke Length and Extension Geometry
Beyond raw power, the physical dimensions of the support are paramount. You must consider the 'stroke length,' which is the distance the piston travels from its fully compressed state to its fully extended state. A mismatch in stroke length can lead to the support bottoming out before the hatch is fully open, or failing to reach full extension, leaving the door partially ajar. Furthermore, pay close attention to the 'extended length'—the distance between the centers of the mounting points when the strut is fully deployed. Even a few millimeters of discrepancy can alter the geometry of the liftgate's movement, leading to jerky motions or premature seal failure.
Mounting Hardware and End-Fitting Types
Lift supports are attached to the vehicle via various end-fittings, most commonly ball sockets, stud mounts, or eyelets. While many replacement supports come with pre-installed ball sockets, it is essential to verify that the diameter of the ball matches your vehicle's existing mounting studs. A loose fit will cause audible clicking and rattling, while a tight fit can prevent the support from pivoting smoothly. High-quality replacements often feature reinforced ball sockets made from high-density polymers or coated metals to resist the friction and environmental wear that occur during thousands of cycles of movement.
Durability and Environmental Resistance
Automotive lift supports are subjected to extreme temperature fluctuations, road salt, and moisture. When evaluating options, look for supports that feature high-quality seals and corrosion-resistant piston rods. A piston rod that is prone to rusting will quickly shred the internal hydraulic seals, leading to gas leaks and total component failure. Premium supports often utilize chrome-plated or specialized coated rods to ensure that the movement remains fluid even in freezing winter conditions or humid summer heat. Investing in a support with superior sealing technology will significantly extend the interval between replacements.
Installation Considerations
While many lift support replacements are designed for a straightforward DIY installation, always check if the kit includes the necessary clips or mounting hardware. Because these components are under significant internal pressure, they should be installed with care. Ensure the mounting points are clean and free of debris to allow the ball sockets to seat perfectly, which prevents lateral stress on the rod during operation.

Quick answers about Suspa Automotive Replacement Shock Lift Supports before you buy.
A standard shock absorbs road impact, while a lift support is an integrated assembly that combines the strut, spring, and mounting hardware to provide both damping and vehicle height stability.
Common signs include excessive bouncing after bumps, leaning to one side, audible clunking during turns, or visible fluid leaking from the strut body.
Yes, high-quality replacement supports are designed to restore the vehicle to its original factory ride height, whereas worn-out components often cause the chassis to sag.
Installing shock supports typically requires a spring compressor to safely manage the tension of the coil spring. Attempting this without proper tools is extremely dangerous.
Many premium replacement supports are sold as 'loaded struts,' which include the spring, mount, and hardware, making them much easier to install than component-only kits.
Yes, any time you replace suspension components like shock supports, you should perform a professional wheel alignment to ensure even tire wear and proper handling.
No, supports are vehicle-specific. You must match the component to your exact year, make, model, and trim level to ensure the spring rate and mounting points are correct.
Heavy-duty options are designed for higher load capacities or off-road use, which typically results in a firmer, more controlled ride compared to standard comfort-oriented supports.
