Alright, let's talk about these gas springs. You're probably here because you need to replace some worn-out lift supports on a hatchback, trunk, or maybe a piece of furniture or machinery. This is a set of two struts, and each one puts out 120 pounds of force. The measurements are key: when fully extended, they're 22.35 inches long (measured from the center of one ball socket to the other). When compressed, they push down to 12.75 inches. The end fittings are 10mm nylon ball sockets, which are super common and should fit right onto the existing mounting balls. Just make sure your old ones match these specs before ordering! These are super straightforward replacement parts – no frills, just solid function. They help lift and hold things open smoothly and safely. Super important to get the right force and length, so double-check your application. A super practical purchase for a DIY fix that'll save you a trip to the mechanic or a big repair bill.
