Powerflex PFR5-426 Rear Differential Rear Mounting Bush for BMW 1 2 3 4 Series (E81 E82 E87 E88 F20 F21 F22 F23 E90 E91 E92 E93 F30 F31 F32 F33 F36) Polyurethane Diff Mount Upgrade

Powerflex PFR5-426 Poly Bush – Rear Final Drive Rear Mount for BMW E81 E82 E87 E88 F20 F21 F22 F23 E90 E91 E92 E93 F30 F31 F32 F33 F36

Transform the back end of your BMW with the Powerflex PFR5-426 polyurethane mount. This uprated rear final drive rear mount bushing replaces the tired factory rubber component that lets the differential move, causing clunks, axle tramp and vague throttle pick-up. The firmer poly construction controls driveline movement, tightening response for cleaner launches, improved traction and a more connected feel on B-roads and track days, while remaining perfectly usable for daily driving.

We’ve installed this part on customer cars across the E- and F-chassis platforms and the feedback has been consistently positive: noticeably crisper driveline behaviour, reduced drivetrain shunt on on-off throttle and far better stability under hard acceleration. If you want a durable, fit-and-forget solution for the rear drive unit mount, this is the go-to choice.

Why upgrade to this poly mount

• Direct replacement for the rear final drive rear mount location on BMW 1 Series, 2 Series, 3 Series and 4 Series
• High-performance polyurethane significantly limits deflection compared to OE rubber
• Controls diff movement to cut wheel hop and axle tramp, sharpen throttle response and improve power delivery
• Long-lasting bushing material for enthusiastic road use and track work
• Balances NVH with performance for a refined, precise rear axle
