Need to replace those worn-out lift supports on your RV, truck canopy, or storage door? These gas struts might be your fix. They’re 20 inches extended (19.7” center-to-center), compress down to about 11.8 inches, and each one delivers 60 pounds of force—so together they’re perfect for lids weighing between 50 and 65 pounds. If your lid’s lighter or heavier, you’ll wanna look at different pressure options. They come as a pair with four ball studs that fit 10mm sockets. Installation’s straightforward, but don’t try to squeeze ‘em by hand—you’ll wreck ’em. If they feel too strong when closing, just mount them a bit closer to the hinges. Great for RV basement doors, truck bed covers, teardrop camper hatches, or even tanning beds. Interchange numbers include 4450 and C1608260. They’ve got a 1-year warranty, so if anything’s off, reach out. Super strong, reliable, and way cheaper than dealer parts.
