PFF76-920BLK Torque Mount Bush Insert is an affordable and easy-to-fit bush insert made from our Black 95A Durometer high-performance material, which works to significantly stiffen the OEM torque mounting for performance on the race circuit or the rally stage. This reduces the amount of engine/trans roll and movement during hard acceleration and gear changing for a more responsive feel, as well as reducing wheel-hop and improving traction. PFF76-920BLK can be fitted alone but will perform most effectively when fitted with our other powertrain inserts (PFF76-923BLK & PFF76-925BLK) as a full set. An increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the engine/transmission and chassis. The harder the material used, the greater the NVH transmitted. Our POWERFLEX PFF76-920 Lower Torque Mount increases the stiffness of the OEM powertrain mounts using our Black 95A material.
