Powerflex PFR5-426 Rear Differential Rear Mount Polyurethane Bush/Bushing for BMW 3 Series E90 E91 E92 E93 (2005-2013) | Final Drive Rear Mount Upgrade | E9x Rear Diff

Rear Final Drive Rear Mount Poly Bush - PFR5-426 - BMW 3 Series E90 E91 E92 E93 2005-2013

Transform rear end control on your E9x with the Powerflex PFR5-426 rear final drive rear mount bush. This uprated poly bush replaces the soft factory rubber at the rear mounting point of the differential to improve traction, reduce diff movement and sharpen chassis response without ruining ride quality.

If your BMW 3 Series is showing signs of wheel hop, clunks on take-up, vague turn-in or uneven tyre wear, this performance bushing is a proven fix. The stable polymer compound keeps the diff precisely located under acceleration and braking so your suspension geometry stays true and the car feels planted and predictable on B-roads, motorway and track day use.

Why enthusiasts choose this upgrade

• Crisper handling and more direct rear axle feel on E90, E91, E92 and E93 models
• Reduces differential wind-up and unwanted movement for cleaner launches and improved grip
• Helps minimise wheel hop and rear steer for better stability in fast road driving
• Durable polyurethane construction that outlasts ageing rubber bushes
• Excellent balance of performance and comfort with minimal increase in NVH
• Backed by the Powerflex Lifetime Warranty for long-term confidence
