Powerflex PFR5-504-22.5 Rear Stabiliser Bar Bush Set for BMW E46 xi/xd (22.5 mm)

Unlock sharper handling and a more planted rear end on your four-wheel-drive BMW E46 with this Powerflex PFR5-504-22.5 polyurethane bush kit. Engineered for a 22.5 mm rear stabiliser bar, these performance-grade bushes curb unwanted movement, keep the suspension geometry consistent and deliver crisper steering feedback. Expect flatter cornering, improved grip, better stability through fast sweepers and a more connected drive on B-roads and motorways.

We run Powerflex on our own builds and our customers keep coming back for them. The upgrade is simple, cost-effective and transforms confidence without ruining ride quality. Polyurethane resists ageing and contamination far better than tired rubber, maintaining performance mile after mile with excellent control of noise and vibration.
