When it comes to maintaining the functionality of your vehicle's rear hatch, trunk, or hood, the gas struts—often referred to as shock lift supports—are the unsung heroes of daily convenience. A failing support doesn't just make a heavy lid difficult to open. It poses a genuine safety risk if a component fails mid-operation. Suspa has established itself as a reliable name in this niche, providing pressurized gas springs designed to counteract gravity and provide smooth, controlled movement. Choosing the right support requires more than just finding something that 'fits'. It requires matching specific physical and mechanical properties to your vehicle's exact requirements to ensure longevity and safety.

2 Truck Upfitters 13" Gas Props (13" Extended, 8.1" Compressed, 30 pounds of Pressure ea) for A.R.E, ATC, Snugtop, Leer Camper Shell/Truck Cap Rear Do...
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 shock lift supports
Understanding Load Capacity and Force Ratings
The most critical factor in selecting a lift support is the Newton (N) rating, which measures the amount of force the strut exerts. Every vehicle manufacturer specifies a precise force requirement for each hinge point. If you select a support with a Newton rating that is too low, the hatch will fail to stay open, potentially crashing down on the user. Conversely, if the rating is too high, you will struggle to close the lid, and you risk putting excessive stress on the mounting brackets, which can lead to structural damage over time. Always verify the force requirements of your specific vehicle's original equipment before making a selection.
Dimensional Accuracy: Stroke and Extension
Lift supports are not one-size-fits-all. You must pay close attention to three specific measurements: the extended length (the distance between the centers of the mounting points when fully open), the compressed length (the distance when fully closed), and the stroke length (the actual travel distance of the piston). A support with a stroke that is too short will prevent your hatch from opening fully, while a stroke that is too long might prevent the lid from latching securely. When replacing worn-out supports, ensure the new units match these dimensions precisely to maintain the intended geometry of the opening mechanism.
Mounting Hardware and Connection Types
The way a support attaches to the vehicle is just as important as the strut itself. Most supports utilize ball-joint sockets or stud-and-clamp mounts. Check your existing hardware to see if the replacement requires a specific diameter for the ball socket. Some high-quality supports come with pre-installed hardware, while others require you to reuse your old clips. If your old clips are rusted or bent, it is highly recommended to purchase a kit that includes fresh mounting hardware to ensure a secure, rattle-free installation.
Build Quality and Seal Integrity
Because these components operate under high pressure and are exposed to the elements, build quality is paramount. Look for supports with high-grade steel rods that feature a corrosion-resistant coating, such as chrome or specialized polymers. This prevents pitting and rust, which can cause the internal seals to fail. A high-quality gas spring should offer a smooth, consistent motion without 'stuttering' or sudden drops. If you live in an extreme climate, prioritize supports designed with robust internal seals that can withstand significant temperature fluctuations without losing gas pressure.

Quick answers about Suspa Shock Lift Supports before you buy.
A shock absorbs bumps and controls spring movement, while a lift support is a complete assembly that includes the spring and strut designed to increase vehicle ground clearance.
Yes, high-quality lift supports increase suspension travel and ground clearance, allowing you to navigate larger obstacles without bottoming out the chassis.
If you are buying a complete strut assembly, the springs are included. If you are only replacing the shock absorbers, you can often reuse your factory springs, though replacing both is recommended for optimal performance.
A higher center of gravity can increase body roll during cornering. However, premium supports are engineered to balance increased height with improved damping to maintain stability.
Lifespan varies based on terrain, but high-end off-road supports are built with heavy-duty seals and valving to endure much harsher conditions than standard factory replacements.
Absolutely. Any change in ride height or suspension geometry alters your wheel alignment, which can cause rapid tire wear if not corrected immediately after installation.
While technically possible for experienced DIYers, installing lift supports requires specialized tools like spring compressors and precision handling to ensure safety and proper fitment.
While the supports themselves don't change your wheel size, the increased lift may require larger tires to take full advantage of the extra clearance.
