Powerflex Transmission Mount Bushing - BMW / 3-Series / 5-Series / Z4 / Toyota Supra | PFF5-4655

PFF5-4655 is a transmission mount that will fit many different models of BMW throughout the years. This is available in 3 different versions. 

• Street: Yellow 70A Durometer
• Performance: Purple 80A Durometer
• Race: Black 95A Durometer

These bushings are designed with street and track in mind to replace the tear-prone soft rubber mounts, which is a common cause of knocking, mis-shifting and over-revving. 

Made using CNC machined Aluminum Caps with captive securing bolts and a Yellow 70A Durometer polyurethane body, they increase stiffness over OE by 150%, while minimizing NVH transmission. 

Aside from our Street Series offering, they are available in our stiffer Purple 80A material for Performance use (260% stiffer) and Black Series 95A material, mainly intended for track use (375% stiffer) for those wanting to further reduce drivetrain movement. The harder the material used, the less deflection they offer and the higher the NVH transmission.
