PAMAGOO 20" Heavy Duty Gas Struts for Lids — 200 lb (890N) Support, L-Brackets, 2-Pack

PAMAGOO 20-inch heavy-duty gas strut pair that supports lids up to ~200 lbs (890N) and includes L-type brackets for quick replacement on RV boxes, bed storage, and DIY lids.

If you need reliable, compact gas shocks to lift and hold a heavy wooden or metal lid without strain, these PAMAGOO gas struts are built for that job. Designed for lids weighing about 185–215 lbs, each 20.04" extended, 12.13" compressed strut supplies consistent force and smooth motion. The set includes hardware and ball-socket ends for easy alignment so you can replace worn springs or upgrade manual lids in minutes.

How do these gas struts make lifting heavy lids easier?

The PAMAGOO struts use pressurized nitrogen and a precision piston to provide counterbalance force, reducing the effort needed to open and hold a lid. They deliver smooth, damped motion so lids don’t slam shut or pop open unexpectedly. Installation of both struts balances the load and improves access to contents.

• Rated at approximately 890N (200 lbs) support per pair for lids 185–215 lbs
• 20.04" extended, 12.13" compressed — correct sizing for intended range
• Ball-socket ends allow 360° rotation for alignment without bending
• Dual-strut setup ensures even lift and stable hold at any angle

Are these gas shocks compatible with my RV storage box or toolbox?

They’re intended as direct replacements or upgrades for heavy lid applications such as RV bed boxes, truck toolboxes, basement access doors, and larger DIY storage lids. Confirm your lid weight falls within the specified 185–215 lbs range and compare extended/compressed lengths to your mounting points before ordering.

• Common uses: RV storage, truck/tool boxes, large toy/tool bins, basement doors
• Works in residential and light commercial settings where heavy lids need support
• Includes L-type mounting brackets and nuts to fit standard ball-stud mounts
• Not recommended to manually compress the strut before installation

What materials and durability features do these PAMAGOO gas springs offer?

PAMAGOO builds these gas springs from high-quality steel with dense sealing materials to minimize leaks and resist wear. They are engineered to work over a wide temperature range and prevent metal-on-metal scratching when installed with the provided fittings. The result is consistent performance across seasons and extended service life compared with cheaper alternatives.

• High-quality steel body and high-density seals for leak resistance
• Stable operation between roughly -14°F and 113°F
• Surface treatments to reduce corrosion and prevent scratches

How difficult is installation and what comes in the package?

Installation is straightforward and requires no special tools; ball-socket ends snap onto the supplied brackets and studs for quick alignment. PAMAGOO supplies two gas struts, four L-type brackets, four nuts, and a simple guide so you can complete the swap in a short amount of time.

• Included: 2 gas struts, 4 mounting brackets, 4 nuts, and an installation guide
• Ball-socket ends enable 360° rotation for accurate positioning
• Typical install time: a few minutes for each strut with common hand tools
