Powerflex Road Series Rear Diff Front Bush Insert for BMW F20 F21 F22 F23 F30 F32 F33 F36
Upgrade your BMW F Series rear end stability and traction with the Powerflex Road Series rear differential front bush insert. This high-performance polyurethane insert fits into the factory rear diff front bush and fills the voids to stabilise the differential under hard acceleration and rapid gear changes. The result is a more connected drivetrain, improved throttle response and a reduction in wheel hop and driveline shunt. Ideal for fast road BMW builds that want sharper, more precise handling without compromising everyday usability.
Engineered from durable polyurethane, this rear differential bush insert is the go-to upgrade for BMW 1 Series, 2 Series, 3 Series and 4 Series F chassis owners who want a simple, effective diff mount upgrade. It is designed to insert into the existing OEM bush, making it a smart, value-driven solution for tightening up the rear subframe and differential mounting points.
At Nforcd we run this upgrade on our own F Series cars and our customers love the transformation in rear axle control and confidence on the road.
