PFF3-1325 Lower Torque Mount Bush is made from our stiffest Black 95A material to provide a durable replacement for the factory rubber bush to give road or tuned vehicles a sharper throttle response and more positive gear-change without compromising ride quality and NVH. An increase in stiffness by 50% over the worn OE rubber bush helps to reduce excessive engine movement caused by the torque reaction of the engine during acceleration and deceleration, one of the biggest causes of wheel-hop on tuned FWD or front-engined vehicles. Please check which type of bracket is fitted to the vehicle before ordering. See the part numbers above and photos below for reference.
