Toyota GR Yaris (2020-2024) Lower Torque Mount Insert - PFF76-920 PFF76-920 Torque Mount Bush Insert is an affordable and easy-to-fit bush insert made from our Yellow 70A Durometer vibration-absorbing material, which works to stiffen the OEM torque mounting. 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. PFF76-920 can be fitted alone but will perform most effectively when fitted with our other powertrain inserts (PFF76-923 & PFF76-925) as a full set. A small 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 yellow 70A material. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
