Powerflex Rear Anti-Roll Bar / Stabiliser/Stabilizer (Sway) Bar Mount Bushes/Bushings 18mm for BMW 5 Series E61 Touring Estate Wagon | Polyurethane ARB Bush Kit | PFR5-4609-18 | Replaces OE 33552283073

Powerflex Polyurethane Rear Stabiliser Bar Bush Kit 18 mm for BMW E61 5 Series Touring

Give your E61 Touring the planted, confidence-inspiring feel it deserves with this rear stabiliser bar bush kit in 18 mm from Powerflex. Replacing tired OE rubber with high-grade polyurethane tightens up the rear axle, keeps geometry in check through bends and delivers flatter cornering, sharper response and dependable stability without adding harshness.

We run these bushes on our own builds at MJ Modifications and our customers love the transformation. Expect crisper steering inputs, better mid-corner composure and a more connected drive on daily commutes and spirited B-road runs alike.

• Direct-fit rear stabiliser mounting inserts for BMW 5 Series E61 Touring estate
