These gas springs are exactly what you need if you're dealing with hatches, lids, or doors that need some assistance staying open! The set comes with two identical gas springs, each measuring 7.5 inches when fully extended (that's center to center of the ball socket ends) and compressing down to 5.5 inches. They provide 30 pounds of pressure per prop, which is that perfect amount of force for many automotive and furniture applications. The end fittings are 10mm nylon ball sockets that work with standard mounting hardware. Whether you're replacing worn-out struts on your car's hatchback, fixing kitchen cabinets that won't stay up, or working on any project where you need controlled lifting assistance, these gas springs deliver reliable performance. The 30-pound pressure is strong enough to hold weight securely but not so strong that it's difficult to close. They're built to last through countless open-close cycles without losing their pressure over time. Installation is pretty straightforward if you're handy with basic tools - just make sure you measure your existing struts carefully to ensure these will fit your specific application. It's one of those replacement parts that seems simple but actually makes a huge difference in functionality when your current struts have given up the ghost.
