Engine movement (deflection) is wasted horsepower, and that power is yours! BMR's suspension wants you to take it back with our polyurethane motor mounts for 1978-1987 GM G-Body. BMRs new motor mounts (MM460) are far superior to the bulky, rubber stock motor mounts, which are designed for comfort, not performance. BMR manufactures its MM460 polyurethane motor mounts from MIG-welded 3/16 -inch plate steel and 95-durometer polyurethane bushings. The kit is completed with Grade 8 hardware.BMR's suspension designed the MM460 to be the perfect (100% bolt-in) motor mount for any power level or application (street performance, drag race, and road race) where engine deflection needs to be reduced. The factory hydraulic motor mounts are designed to dampen engine vibration, giving you the smoothest and most comfortable experience possible. Unfortunately, this does little to limit engine movement. This deflection means lackluster throttle response, slower reaction times, and less accurate shifts in manual-equipped cars. BMRs MM460 polyurethane motor mounts limit engine deflection, while isolating much of the engine vibration from the vehicles occupants. This means you wont feel a big increase in NVH. The reduction in deflection leads to more power transferred to the tires, improving your driving experience on both the street and track. And less drivetrain movement means more accurate shifts as you row through the gears. When performance is a must, rely on BMR's suspension!BMR's suspensions MM460 polyurethane motor mounts are available in red and black hammertone powdercoat for long-lasting good looks in your cars most harsh environment. Installation time is about 2-3 hours. Proudly made in the U.S.A.
