Powerflex PFR5-1927 Rear Differential Front Mount Insert Bush Kit for BMW 2 Series F22/F23 (218i-240i, M235i/M240i) - Polyurethane Diff Bush/Bushing Upgrade - Final Drive Front Support - Replaces OE 33316792513

PFR5-1927 Polyurethane Rear Final Drive Front Mount Insert Set for BMW 2 Series F22 F23

Transform the rear end of your BMW 2 Series F22 or F23 with this Powerflex PFR5-1927 front mounting insert set. These precision urethane inserts locate in the voids of the factory rubber mount to control differential movement under load, tightening up the drivetrain for cleaner launches, stronger traction and a more connected feel on the road or at a track day.

If you are chasing sharper handling, reduced wheel hop and less rear axle shunt on throttle changes, this diff support insert is the go to upgrade. Our team at MJ Modifications has fitted these on customer cars and our own builds, and feedback has been consistently positive for fast road use without the harshness of solid mounts.

What you will notice

• More stable rear axle under acceleration and braking
• Reduced torque wind up and minimised diff movement for crisper responses
• Improved rear end grip and confidence when cornering
• Long lasting polyurethane that outperforms and outlives ageing rubber
• Designed for performance road driving with optional Black Series for track focused builds

How it works

The insert fills the gaps in the OE bush, limiting excessive compliance in the differential carrier without the need to press out the original mount. The result is better driveline control, less clunking from the rear and a more precise, planted feel from your BMW 2 Series chassis.

Why Powerflex polyurethane

Engineered polyurethane resists oil, road salt and heat, keeping geometry consistent for predictable handling. It maintains drivability while cutting unwanted movement in the subframe and driveline, delivering the sweet spot between comfort and control on the F22 and F23 platforms.
