Vepagoo 42 in Gas Strut 40lb Pair - Heavy Duty Lid Support

In this review the Vepagoo 42 in gas strut pair is evaluated for anyone fitting or replacing heavy lid supports on tonneau covers, RV doors, trailer caps or custom wood lids. The single biggest reason to buy is the clear heavy-duty specification: each strut offers 40 lb (178 N) of force with a 42 in extended length, which makes them a straightforward swap for larger lids and covers where rugged, long-stroke support is needed. Installation is simple and the set of two gives balanced lift for most medium to large lids.

Key Features

• 42 in extended length: The long 42 in stroke gives plenty of reach for tall or deep lids and helps achieve the recommended 1/2 to 2/3 of lid length for correct operation.
• 40 lb/178 N force: Each strut is rated for 40 lb, so a matched pair can support lids up to the combined pressure recommendation and reduce manual lifting effort.
• Set of two: Supplied as a matched pair to ensure balanced lift and consistent performance on both sides of the lid.
• Ball end and threaded fittings: Includes 13 mm ball end joint and 10 mm screw thread for common mounting options and straightforward hardware compatibility.
• All-weather performance: Built to perform in hot or cold environments so outdoor installations like tonneau covers and trailer doors remain reliable.
• Quick installation: Designed for a fast 5 minute installation in many applications, making it an easy DIY replacement for heavier original struts.

Who It's For

This product suits DIYers and vehicle owners who need a heavy-duty replacement for long lids such as truck bed covers, tonneau covers, RV kitchen doors, or trailer caps. It is particularly useful when the lid length is medium to large and needs a strut roughly 1/2 to 2/3 of that length for correct geometry and operation.

Those who should look elsewhere include users with very light lids that require lower force or very short lids where a 42 in extended length would be impractical; also, confirm ball end and thread sizes match your existing brackets before buying since custom mounts may be required for unusual fittings.

Pros & Cons

Pros

• Heavy-duty 40 lb force per strut provides solid lift and restores functionality to larger lids.
• Long 42 in extended length fits many tonneau and trailer lid applications without modification.
• Easy installation and common 13 mm ball end and 10 mm thread make mounting simple for most users.
• Durable performance across temperatures so outdoor use is practical.

Cons

• Some users report mixed experience with closing ease, so exact feel depends on lid weight and mounting geometry.
• Large extended length may be unsuitable for short lids or confined mounting spaces.
