Powerflex PFR5-726 Rear Diff Mount Bush/Bushing (Final Drive Rear) for BMW 5 Series E60 Saloon 2003-2010 - Polyurethane Polybush Upgrade - Replaces OE 33176770825 - Rear Axle Differential Hanger Mount

Rear diff back mount poly bush upgrade for BMW E60 5 Series Saloon - Part PFR5-726

Give your E60’s rear end the precision it deserves. This premium polyurethane rear final drive rear mount bushing replaces the soft, ageing factory rubber to cut deflection, calm the rear under load and deliver confident, planted grip on British roads. Expect tighter response, cleaner power delivery and a more connected feel without sacrificing day-to-day comfort. Backed by the Powerflex Lifetime Warranty, it is a fit-and-forget upgrade built to last.

• Transforms rear end composure for crisp turn-in and predictable balance
• Improves traction out of bends and stability during hard braking
• Keeps the rear geometry consistent for more even tyre wear
• Reduces rear-end squirm, wheel hop and driveline shunt
• Durable polyurethane resists oil, heat and road contaminants far better than OE rubber
• Refined NVH control suitable for daily drivers and spirited road use

Why this poly bush

Under acceleration and over rough surfaces, the factory mount can flex, letting the differential move and unsettling the car. This upgraded bushing limits unwanted movement so the suspension can do its job properly. The result is a more stable rear axle, clearer feedback through the chassis and confidence-inspiring behaviour in all conditions.
