Powerflex PFR5-726 Polyurethane Rear Final Drive Support Bush for BMW E61 5 Series Touring

Sharpen the back end of your BMW E61 5 Series Touring with this polyurethane rear final drive support bush from Powerflex. By replacing the tired factory rubber with a tough, precision-moulded poly mount, you lock down the differential, tighten driveline control and restore crisp, confidence-inspiring handling on road or track. Expect cleaner power delivery, reduced axle hop and a more planted estate that feels great mile after mile.

Why upgrade this mount on your E61 Touring

• Stiffens the final drive support to reduce unwanted movement under load
• Delivers more consistent traction and cleaner launches with less wheel hop and tramp
• Keeps alignment true for better tyre contact and predictable cornering
• Polyurethane resists oil, fuel, salt and heat for long service life
• Improves steering feel and rear-end stability without the sag of ageing rubber
• Backed by Powerflex Lifetime Warranty for peace of mind

Typical issues this bush helps resolve

• Clunks or thuds from the driveline when taking up power
• Loose or vague rear-end behaviour during acceleration and braking
• Uneven tyre wear caused by geometry shift under load
• Vibration and shunt from a perished differential mount
