40 Inch 200Lb Gas Struts Lift Support for Tonneau Cover - Strong Lift

In this review the reviewer assesses a pair of 40 in, 200lb gas struts intended as replacement lift supports for tonneau covers, toolbox lids and similar hinged panels. The single biggest reason to consider these is straightforward: each strut delivers a firm 200lb/890N force and extends to 40 in, so they keep medium-weight lids open reliably and resist hand compression. The package and testing claims make them a practical choice for DIYers who need robust, weather-resistant support for truck beds, camper hatches and storage lids.

Key Features

• Force and length: Each strut provides 200lb/890N of lift force and extends to 40 in, which offers confident support for heavier lids and covers.
• Compressed length: The 22 in compressed length allows fitting on many common lids where space is limited when closed.
• End fittings: The 13mm ball stud endings make installation compatible with standard ball-socket mounts and streamline replacement of original struts.
• Application range: Rated to hold lids at roughly 90-150 degrees and suitable for 160-220 lb loads per strut, making them useful on tonneau covers, toolboxes and camper hatches.
• Durability claims: Manufacturer testing and weather-resistance claims suggest these will work in varied climates and outdoor conditions.
• After-sales support: The included installation guide and 12-month support promise help if there are fitment or performance questions.

Who It's For

These gas struts suit vehicle and trailer owners replacing worn supports on tonneau covers, truck bed lids, toolboxes or camper kitchens, plus DIYers building storage benches or hatch doors that need a strong, reliable lift. The 40 in extended length and 200lb force are well matched to medium to heavy lids where a stiff, positive open is needed.

Owners of very light lids or precision interior cabinetry that require soft, slow motion should look elsewhere for lower-force, damped gas springs. Also, if your application requires uncommon end fittings or a compressed length under 22 in, confirm measurements before ordering.

Pros & Cons

Pros

• High lift force gives a confident hold for heavier lids and tonneau covers.
• Standard 13mm ball stud ends simplify replacement and reduce installation time.
• Weather-tested design and manufacturer backing provide reassurance for outdoor use.

Cons

• Some users report variable long-term retention of force, so longevity may vary by use and environment.
