No one does body lift kits better than Performance Accessories. We are proud to offer the most complete line of body lift kits in the world. When you purchase a lift kit for your truck you want to install it, with no problems. We work hard to make that reality. Not only do we design every body lift kit right here in Chino Valley AZ, USA, we also manufacture all the parts (spacers, steering extensions, bumper brackets, etc.) and assemble all of the kits right here as well.
