If your vehicle's rear liftgate is getting heavy and won't stay up anymore, these Stabilus Sachs lift supports are exactly what you need! This set includes two high-quality gas struts that replace your worn-out OEM units and restore that smooth, easy operation your liftgate should have. The extended length measures 21.81 inches from center mount to center mount, and these are direct replacements for OEM numbers 74820TX4A21, 74820-TX4-A21, 880515, and SG265005. The quality construction meets or exceeds original manufacturer specifications, so you're getting performance that matches what came with your vehicle when it was new. Gas struts naturally lose pressure over time - even just sitting on shelves - but these are newly produced units with fresh pressure that will hold your liftgate securely in place. Installation is typically straightforward if you're comfortable with basic automotive maintenance, and having both struts replaced at the same time ensures balanced performance. The limited lifetime warranty gives you peace of mind that these are built to last. No more worrying about your liftgate suddenly dropping while you're loading groceries or having to prop it up with a stick! Your vehicle's convenience features should work properly, and these quality replacement struts deliver the reliable performance you expect from your power liftgate system. It's one of those maintenance items that makes daily life so much easier when it's working correctly.
