Powerflex PFR5-420 Rear Subframe Front Mount Bush Kit for BMW 3 Series E90 E91 E92 E93 (2005-2013) - Polyurethane Rear Cradle/Axle Carrier Bushings - E9x Performance Suspension Upgrade - Replaces OE 33316758259 - Pack of 2

Rear Axle Carrier Front Mount Bush Kit – PFR5-420 – BMW 3 Series E90 E91 E92 E93 2005 to 2013

Give your E9x chassis the precise feel it deserves. The PFR5-420 polyurethane rear cradle front mounts replace soft, ageing factory rubber and dramatically reduce unwanted movement at the front position of the rear subframe. The result is tighter rear-end control, cleaner geometry under load and a more planted BMW on B-roads, motorways and track days.

We run these bushings on our own cars and our customers consistently report a noticeable improvement in stability, braking confidence and traction without harshness. If you are upgrading a daily driver or building a fast-road setup, this is a proven suspension upgrade that transforms how the car responds.

Why this upgrade works

• Reduces subframe deflection for sharper turn-in and consistent alignment control
• Improves rear axle stability under acceleration and braking
• Durable polyurethane resists oil, heat and age-related degradation far better than OE rubber
• Balances performance with NVH control for comfortable road use
• Helps promote even tyre wear by keeping the rear geometry in check
• Covered by the manufacturer’s Lifetime Warranty for peace of mind

Road feel you can trust

Worn rubber bushes allow the rear cradle to shift, which can cause nervous handling, tramlining and vague responses. Swapping to these polyurethane mounts tightens everything up, helping your BMW hold a line through corners and feel composed over rough surfaces. Expect a more direct, confidence-inspiring drive.

Full replacement or insert

PFR5-420 is a full replacement bush set. If you prefer inserts that fit into the original housing, choose PFR5-419.
