Powerflex Toyota GR Yaris (2020-2024) Upper Gearbox Mount Insert

• Developed for ultimate performance using the toughest materials
• Engineered for the most accurate control of chassis geometry
• Manufactured to be easily fitted without the need for special tools
• Powerflex Black Series bushes are manufactured using a 95 Shore A compound to provide maximum control of chassis geometry.
• This compound can be up to 80% more resistant to load than standard rubber and 25% stiffer than our purple performance material.

• PFF76-923 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.
