Toyota Yaris GR PowerFlex Upper Gearbox Mount

Toyota Yaris GR PowerFlex Upper Gearbox Mount

SKU: NG-PFF76-923

PowerFlex Upper Gearbox Mount Insert for the Toyota Yaris GR 


PFF76-923 - YELLOW STREET Upper Gearbox Mount 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 upper gearbox mounting. This reduces twist of the engine under acceleration and during gear changes, giving the pedals a more direct feel, as well as reducing wheel-hop and letting you get the power down that little bit quicker. We recommend fitting PFF76-923 alongside our other Yaris GR powertrain inserts (PFF76-920 & PFF76-925), as they perform much more effectively as a full set. There will be a minor increase in NVH when stiffening the powertrain mountings.


PFF76-923 BLACK - RACE - Max Stabilty. Vibration-NVH expected. Track use only recommended
