PAMAGOO 18.7 inch 40 lb gas struts are a two-piece replacement set designed to lift and hold Leer/ARE camper shell and pickup topper rear windows and tool-box lids with reliable 40 lb (125 N) force.

These PAMAGOO gas shocks (models C16-20651 and C16-33313) offer a direct-fit, high-durability solution for camper shell and canopy rear windows, tailgate-style toppers, and similar hinged panels.
