Powerflex PFR5-1927 Rear Final Drive Front Insert Pair for BMW 3 Series F30, F31, F34 Gran Turismo

Sharpen your BMW 3 Series rear-end control with this Powerflex PFR5-1927 insert pair. Designed to sit inside the original rear final drive front mount, these performance polyurethane inserts limit unwanted movement in the driveline, giving a more planted feel, cleaner traction on acceleration and crisper responses without sacrificing everyday comfort.

Why upgrade this mounting point

• Reduces differential shift under load for a tighter, more connected driving feel
• Improves traction and stability, helping curb axle tramp and driveline shunt
• Helps tyres maintain better contact with the road for predictable cornering
• Durable polyurethane resists oil, salt and heat far better than ageing rubber
• Insert design works with the factory bush, keeping noise and vibration civilised
• Powerflex quality with a Lifetime Warranty for peace of mind
