Is the hatch on your RV, camper, or boat not staying up like it used to? These gas struts (also called gas springs, props, or shocks) are the exact replacement you need. You get a set of two, each providing 150 pounds of lifting force. The important specs: They're 26.34 inches long when fully extended (measured from the center of one ball socket to the other), and they compress down to 16.5 inches. Both ends have 10mm ball sockets, which is a super common fitting. These are what hold up those heavy exterior storage compartment doors, engine hatches, or even some truck bed covers. Replacing worn-out struts is usually a very simple DIY job—just pop the old ones off (be careful, they're under pressure) and snap these new ones into place. No more having the door slam down on your head or holding it up with a stick! Makes accessing your gear safe and easy again. Always replace struts in pairs to ensure even lifting force. Check your old struts' length and force rating to make sure these match. A small, affordable fix that makes a huge difference in usability. Get your storage space back in working order.
