ST460M60 44in 60lbs Gas Struts Pair for Tonneau Cover and RV - Heavy

In this review the ST460M60 44in gas strut pair is judged primarily as a heavy duty replacement for larger covers and lids; it is best for DIYers who need substantial lift force without custom fabrication. The reviewer finds the single biggest reason to buy is the combination of long 44 in extended length and a strong 267 N (60lbs) push per strut, which suits tonneau covers, RV beds and truck bed hatches where side length exceeds 50 in. Installation advice and real-world fit matter here, so read the guide and check your lid weight before purchase.

Key Features

• Length and force: Each strut extends to 44 in and delivers 267 N (60lbs) of force, providing ample lift for large lids and covers.
• Compatibility guidance: The seller recommends fitting to covers with side length over 50 in and target weight of 80-120lbs per strut, which helps buyers match these to their project.
• Durable construction: Built from corrosion resistant stainless steel with hydraulic oil seals for better weather resistance in outdoor conditions.
• End fittings: Each strut terminates on a 13mm ball stud for common mounting hardware, simplifying replacement and retrofit tasks.
• Package contents and support: The set includes two struts, an installation guide and a 12-month warranty with 24 hour customer service for peace of mind.
• Temperature tolerance: Rated for harsh environments down to roughly minus 104F and heavy rain conditions, making them suitable for outdoor vehicle use.

Who It's For

The ST460M60 pair is ideal for vehicle owners and DIYers who are upgrading or replacing lift supports on tonneau covers, RV bed lids, truck hatches, toolbox lids and similar large closures that exceed 50 in side length. Installers who need a robust stainless steel option with conventional 13mm ball stud ends will appreciate the fit and mounting simplicity.

These gas struts are not for very light lids under about 80lbs per strut or for projects requiring compression adjustment by hand; the units cannot be compressed safely by hand. If the lid or cover is significantly lighter than the suggested range or needs a different end fitting, consider a different size or consult the seller before purchasing.
