The upper and lower bushing kit comes complete with the appropriate size sleeves for the '73 Chevy C10 control arms as well as Formula 5 Prelube, a slippery substance used to lubricate the bushing to quell squeaks and reduce friction at the pivot points of the suspension. The Hyper-Flex polyurethane bushings will last a long time thanks to their resistance to breaking down under attacks from oil, fuel, moisture, and road salt.
