Powerflex Black – Lower Torque Mount Insert for Toyota GR Yaris

The Powerflex Black Series lower torque mount bush insert (PFF76-920BLK) is the ideal solution for stiffening the original OEM engine/gearbox mount on the Toyota GR Yaris in high-performance applications such as circuit driving, rallying and track days.

Made from Powerflex's special 95 Shore A Black Series polyurethane compound (the hardest grade in the Powerflex range), this insert fills the voids in the original rubber bush, drastically limiting powertrain movement and twist under hard acceleration and during fast gear changes. Reducing this movement provides a significantly more direct throttle response, reduces front-wheel wheel hop when launching and transfers power to the road more quickly and effectively.

Installation is straightforward and cost-effective because the insert fits inside the original OEM mount (OEM part number: 12363-18010), without requiring replacement of the complete arm. It can be installed on its own or combined with the other Powerflex powertrain inserts for the Toyota GR Yaris (PFF76-923BLK and PFF76-925BLK) for comprehensive drivetrain control.
