Powerflex BMW Rear Diff Rear Mounting Bush – PFR5-426BLK
Upgrade the rear differential mounting on your BMW with the Powerflex rear diff rear mounting bush. This BMW rear differential bush is a proven performance upgrade for E81, E82, E87, E88, F20, F21, F22, F23, E90, E91, E92, E93, F30, F31, F32, F33 and F36 platforms. Built from high-performance polyurethane, the Powerflex PFR5-426BLK rear diff mount bush replaces the soft, ageing OEM rubber bush to deliver stronger diff location, better traction and a sharper, more connected rear end. Ideal for fast road, track day and drift use, and a popular choice for tuned and standard cars alike.
Why choose this BMW rear differential mounting bush
- Reduces rear differential movement for crisper throttle response and cleaner gear changes.
- Improves traction, corner exit stability and launch consistency by controlling diff wind-up.
- Durable polyurethane construction resists oil, heat and ageing better than OEM rubber bushes.
- Helps minimise wheel hop and diff clunk, enhancing confidence under power.
- Direct replacement rear diff bush for straightforward installation and long service life.
We use Powerflex bushes on our own cars and customer builds, and feedback from BMW 1 Series, 2 Series, 3 Series and 4 Series owners has been consistently positive. Expect a more planted rear axle and a tighter, more precise driving feel.
