This is a pair of stabilizer links, also called sway bar or anti-roll bar links. Each link has a ball joint stud with nut at the top and an eye with a through-bolt at the bottom, with black rubber boots covering the joints. The set shown includes two links with their mounting hardware, and they look new and clean with no cracks or torn boots. They can fit the front or rear depending on the vehicle, so please match them to your car before ordering. Check the OE or part number, the center-to-center length, and the stud and bolt sizes to confirm correct fitment. It is best to replace both left and right links together, as shown in the photo.
