Is your car's rear hatch or liftgate struggling to stay open, or sagging dangerously? It's probably time for new lift supports! This is a PAIR (2 pieces) of gas-charged struts designed to safely and reliably hold your hatch open. They have an extended length of 14.5 inches (measured center-to-center of the ball sockets) and compress down to 9.5 inches. Each strut provides 40 pounds of lifting force, and together they'll get your hatch popping up and staying up like it's brand new. The end fittings are standard 10mm ball sockets, which are super common for many vehicle applications. Super easy to install with basic tools—usually just a socket wrench or pliers. Just make sure to measure your old struts (length and force) to ensure these are the right replacements for your specific car, truck, or SUV model. Restore safety and convenience to your vehicle with this affordable, heavy-duty set of lift supports!
