The most compelling reason to buy is the raw force - each strut is rated at 1334 N (about 300 lbs) and comes in a matched pair, so it is designed to handle heavy panels that are more than 72 in side length and weigh roughly 240-330 lbs per strut application.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eForce and size:\u003c\/strong\u003e Each strut provides 1334 N (300 lb) of lift across a 36 in extended length, giving consistent, high-force support for heavy lids.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatched pair:\u003c\/strong\u003e The set includes two identical gas struts so that both sides of a cover operate with balanced lift and predictable motion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion resistance:\u003c\/strong\u003e Constructed from stainless steel and corrosion-resistant materials to endure outdoor use and harsh weather conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e13 mm end fit:\u003c\/strong\u003e The 13 mm ball stud termination simplifies installation on common brackets and makes the strut compatible with standard ball-style mounts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide temperature tolerance:\u003c\/strong\u003e Rated for very low temperatures, the struts are claimed to remain functional in conditions down to around minus 104F, suitable for cold climates.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation support:\u003c\/strong\u003e The package includes an installation guide and access to 12 months of customer support for fitment questions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis product is aimed at vehicle owners, RV and camper DIYers, and workshop installers who need a robust, high-force pair of gas springs for heavy tonneau covers, floor hatches, trap doors, shell toppers and camper kitchen lids.
