Powerflex Transmission Mount Bushing - Street

Product Details

Deflection Recovery Architecture: Powerflex Performance Transmission Mounts

Drivetrain twist is a critical liability on the street and at the track. Under aggressive throttle application and heavy threshold braking, factory rubber transmission mounts distort heavily under torque load. This alignment migration twists your shift linkage, causing knocking, sluggish gear engagement, and the dangerous threat of a mechanical over-rev. The Powerflex PFF5-4655 Transmission Bushing Kit is a zero-compromise mechanical solution for RWD platforms looking to secure their powertrain geometry.

Featuring a 70A durometer polyurethane core shielded by CNC-machined aluminum caps, these units yield a 150% structural stiffness increase over OEM rubber. By controlling horizontal and vertical transmission deflection, shifting forces are executed seamlessly across the gate, and rotational energy is directly transferred to the rear wheels. This is a critical preventative reliability item for tuned street builds and dedicated track weapons alike.

Technical Features:

• Powertrain Stability: Limits transmission deflection by 150% to optimize shift gate precision.

• High-Tolerance Hybrid Materials: Built with premium polyurethane and hard-anodized aluminum top caps with captive securing bolts.

• Anti-Over-Rev Insurance: Minimizes engine pitching to keep manual shift linkage paths perfectly true.

• Broad Application Fitment: Spec'd out for a vast array of RWD generations including E36, E46, E9X, F30, and A90 chassis.
