Urethane bushings are far superior to the stock rubber. Standard urethane bushings kits do not have any means of lubrication after they are installed. Our urethane bushing kits come with special sleeves with a groove for the grease to travel around the bushings. Grease fittings are also supplied to enable the greasing of the urethane bushings, eliminating those annoying squeaks. Lube the urethane bushings with moly-grease and/or general purpose grease. Bushings come in Red or Black (depending on availability).
