Powerflex Upper Gearbox Mount Insert - Black Series - PFF85-441BLK

PFF85-441 uses our Yellow 70A durometer material, providing an excellent balance of strength and compliance for improved performance, whilst limiting NVH transmission into the cabin. This part is recommended for Petrol models and high-torque tuned Diesel models. A small increase in NVH, usually at idle, should be expected when stiffening the connecting mount between the drivetrain and chassis. The harder the material used, the greater the NVH transmitted. Reducing engine/trans movement by way of upgraded inserts has the following benefits - Sharper throttle response - More accurate gear changes - Reduced wheel-hop - Improved Traction - Prolonged mount life. Does not fit S3 8L.

Our Heritage Collection bushings utilize the same durometer polyurethane as the Street bushings, but are a dark grey color that mimics the OEM rubber bushings to satisfy the purest of purists.
