Powerflex Black Series Transmission/Gearbox Mounting Bush PFF5-4655BLK for BMW RWD 1 2 3 4 5 Series (E36 E46 E60 E82 E90 F10 F20 F30, M2 M3 M4 M5) 95A Polyurethane Motorsport

Powerflex Black Series PFF5-4655BLK Gearbox Support Bush - BMW RWD Performance Upgrade

Lock down your drivetrain and transform shift precision with the Powerflex Black Series PFF5-4655BLK gearbox support bush. Built for serious track, drift and fast-road use, this race-grade 95A polyurethane mount replaces the soft factory rubber that allows excessive movement, causing driveline knock, vague shifts and over-rev under load. For rear-wheel-drive BMW applications, this is the go-to upgrade for crisp gear engagement and confidence on throttle.

The Black Series construction combines CNC machined aluminium end caps with captive bolts and a high-durometer polyurethane core that is 375% stiffer than OE. The result is tighter powertrain control, improved shift accuracy and superb durability against heat, oil and road contaminants. We run these mounts on our own builds and customer cars with consistently excellent feedback on feel and longevity.

Why enthusiasts choose this mount

• Race-focused polyurethane bushing to control gearbox movement on BMW RWD platforms
• 95A Black Series compound for maximum stability and sharper gear selection
• CNC aluminium caps with captive hardware for a precise, secure fit
• Approximately 375% stiffer than standard for reduced drivetrain lash
• Helps cure clunking under load, missed shifts and unwanted engine flare
• Ideal for track days, drift, time attack and fast-road builds seeking consistent shift feel
• Proven by our team and customers for robustness and repeatable performance

For a fully controlled powertrain setup, pair this gearbox mount with the Powerflex PFF5-4650 Tuneable Engine Mount on suitable E36, E46 and E90-series models.
