Powerfex Transmission Mount Bushing - Performance

Product Details

Deflection Eradicated: Powerflex 80A Tuned/Track Transmission Mounts

Drivetrain deflection is an absolute performance killer that ruins shift precision and risks catastrophic over-revving. Under track-level lateral loads and hard acceleration, soft factory rubber transmission mounts flex excessively, letting the gearbox housing physically pitch out of alignment with your shift linkage. The Powerflex PFF5-4655P Transmission Bush Set is a track-validated solution engineered to stabilize your transmission's centerline.

Formulated from a high-density Purple 80A durometer polyurethane, this mount assembly delivers a massive 260% increase in torsional stiffness over stock rubber. The load is structurally distributed via CNC-machined aluminum caps with captive securing studs, preventing mount deflection under severe engine torque. This kit keeps the mechanical link between your shifter and gearbox perfectly stable, delivering crisp, zero-compromise engagement across the gate at the absolute limit. It is a mandatory reliability asset for tuned street cars and weekend track weapons alike.

Technical Features:

• 260% Stiffness Profile: Heavy-duty upgrade designed to permanently stabilize transmission alignment under track loads.

• 80A Durometer Polyurethane: Engineered to withstand extreme exhaust radiant heat and mechanical fatigue without breaking down.

• CNC Machined End Caps: Integrated aluminum framing optimizes the load distribution curve across factory crossmember footprints.

• RWD Compatibility: Direct press-fit swap for factory cross-reference part numbers 22316799331, 22316875904, and 22322282340.
