UMI high-durometer polyurethane rear end housing bushings replace factory rubber rear end bushings for 1965–1987 GM applications. The kit includes two bushings and two polyurethane washers to prevent lateral movement and walking. These bushings resist dry rot and cracking, improving ride quality and performance for street-driven or track-used vehicles and are made in the USA.
