Reduce wheel hop and increase traction and handling ability with differential housing bushings from BMR Suspension. With three new kits for GM A-body, B-body, and G-body, BMR has the solution to stock, worn out, or rotted differential bushings. The new BK kits (BK043 – 1964 GM A-body, BK044 – 1965-1972 GM A-body and 1978-1987 GM G-body, and BK045 – 1991-1996 GM B-body) are designed for street performance, autocross, drag race, and road race applications, or as a superior stock replacement bushing.

The 95-durometer polyurethane bushings are internally fluted, which allows grease to coat the inner sleeve and thrust surfaces, but also keeps grease in the bushing under high-load situations. BMR’s BK043/44/45 differential bushings are designed to handle the high compression loads of hard launches and high horsepower, while offering plenty of articulation for great handling. When performance is a must, rely on BMR Suspension! Proudly made in the U.S.A.!
