Global West's Interloc bushings are designed to replace the factory bushings. They feature a self-locking design that sandwiches the frame and holds it in position. This design eliminates frame to body slippage. They are especially recommended if you are installing a subframe connector. Six Inteloc bushings are supplied with each kit. This includes two radiator support and four main body bushings. Kits for use with Global West Subframe Connectors come with four bushings (two core support and two front body mounts). The rear two bushings come with the subframe connectors. New hardware included.
