PAMAGOO 12" 40 lb Gas Struts for Tool Boxes & Camper Shells — 2-Pack, 12.2" Extended Smooth Lift

PAMAGOO C16-11028 gas struts are a 12-inch, 40-lb pair of replacement shocks designed to lift and hold tool box lids, truck topper windows, and camper shell side/rear windows safely and smoothly.

If your Weatherguard or similar aluminum truck toolbox, Leer side window, or pickup camper shell is sporting worn, weak, or leaking shocks, these PAMAGOO replacement gas springs restore controlled opening and secure holding without propping the lid. Each kit contains two matching 12" (12.2" extended, 7.48" compressed) gas struts rated at 40 lb (178 N) each and fits a wide range of OEM numbers including C1611028, ML1540, SL15-40 and 7009-2PK. Installation is straightforward—clips pop off and the new struts snap into place—so you can be back on the road with reliable lift support in minutes.

How do these gas struts fit my toolbox or camper shell?

These struts are engineered to match the common mounting length and force needed for many aluminum tool box lids, Leer side windows, and pickup topper rear windows. Check the listed OEM part numbers and measure extended/compressed lengths to confirm fitment.

• Extended: 12.2 inches; compressed: 7.48 inches.
• Force: 40 lb (178 N) per strut — suitable for light-to-medium lids and windows.
• Compatible OEM numbers listed: C1611028, ML1540, SL15-40, 7009-2PK, and more.

What tools and time are required to install the PAMAGOO struts?

Installation is quick and requires only basic hand tools. Most installs take about five minutes for each strut—remove the retaining clip on the old shock and snap the PAMAGOO unit onto the existing ball studs.

• Required tools: flat-head screwdriver (to remove clips) and optionally pliers for tight clips.
• Installation steps: remove clips from old strut, compress slightly if needed, snap new socket onto ball stud, replace clip.
• No drilling or permanent modification needed when replacing like-for-like mounts.

How will these replacements change daily use and safety?

Replacing failing shocks with these gas struts restores smooth, controlled lifting and dependable holding, eliminating the need for temporary props and reducing the chance of sudden lid slams. That improves accessibility and lowers injury risk when accessing tools or cargo.

• Prevents lids and windows from slamming shut—safer loading and unloading.
• Ensures steady open position for hands-free access to contents.
• Pairs sold together maintain balanced lift on both sides of the lid/window.

What warranty and after-sale support does PAMAGOO provide?

PAMAGOO backs these struts with an 18-month support period. Customer service is available to answer fitment or installation questions before and after purchase so you can replace shocks confidently.

• 18-month support for product questions and troubleshooting.
• Compatible with a wide range of part numbers to simplify ordering.
• Clear specifications included to confirm correct replacement length and force.
