BMR MM460 polyurethane motor mount kit for 1978–1987 GM G-Body is a complete upper and lower set built from MIG-welded 3/16-inch plate steel and 95-durometer polyurethane bushings with Grade 8 hardware. The 100% bolt-in kit reduces engine deflection compared with stock hydraulic mounts, improving throttle response and shift feel while isolating much of engine vibration. Installation is about 2–3 hours; made in the USA.
