Does your RV or camper cargo door slam shut or just not stay open anymore? This pair of gas struts (also called lift supports or shocks) is likely the fix. Each strut has an extended length of 15 inches (measured from the center of one ball socket to the other) and compresses down to 9.75 inches. They provide 100 pounds of lifting force per strut, so the pair works together to hold your door securely open. The end fittings are 10mm ball sockets, which are common for many RV applications, including some Winnebago models. These are sold as a set of two, which is usually what you need for a balanced door. Always compare the length, compressed length, end fitting type, and force rating to your old, worn-out struts to ensure a perfect match. Replacing them is usually a simple job with basic tools – just be cautious as the old struts may still have some pressure. Get your door working smoothly and safely again!
