Powerflex Transmission Mount Bushing - Black Series

Product Details

Zero Compromise Powertrain Control: Powerflex Black Series 95A Mounts

Drivetrain deflection is a direct threat to shift accuracy and track performance. Under aggressive threshold braking or high-load acceleration, factory rear-wheel-drive BMW transmission mounts deflect under load, causing powertrain shift. This misalignment across the transmission tunnel is a leading cause of mechanical knocking, missed gear selection, and catastrophic over-revs at the limit. The Powerflex PFF5-4655BLK Bushing Set is a zero-compromise motorsport solution designed to secure your gearbox geometry.

Engineered specifically for dedicated track, drift, and maximum performance builds, these mounts feature an ultra-hard 95A durometer polyurethane core structurally reinforced with CNC-machined aluminum caps and captive hardware. This combination yields a 375% increase in structural stiffness over stock rubber. Drivetrain slop is completely neutralized, ensuring instantaneous power transfer and predictable, crisp shift gating under severe racing conditions.

Technical Features:

• 375% Rigidity Blueprint: Engineered to completely resist gearbox twist under maximum cornering and engine torque.

• CNC-Machined Aluminum Caps: Distributes clamping force equally while captive securing bolts prevent thread backing.

• Motorsport Compound: Elite 95A durometer polyurethane handles extreme radiant exhaust heat and fluid contamination without expanding or softening.

• Broad RWD Fitment: Direct replacement upgrade for E36, E46, E9X, F22, F3X, F8X M2/M3/M4, and Z-Series chassis.
