Shop Powerflex suspension bushes, differential mounting bushes and BMW F8x dual differential bracket kits at Nineteen72 Performance. Select the exact vehicle, mounting position and product specification before choosing between an individual bush, a bush set or a bracket package.
BMW F-series and G-series parts are not interchangeable by default. Our F8x differential bracket packages cover the listed F87 M2, F80 M3 and F82/F83 M4 applications. G8x M2, M3 and M4 owners should use the separately identified G-series bush listings below.
BMW differential bushes: F8x versus G8x
| Application | Front of rear differential | Rear of rear differential |
|---|---|---|
| F87 M2, F80 M3, F82/F83 M4 | PFR5-4025 front bush set | PFR5-4026 rear bush |
| G87 M2, G80/G81 M3, G82/G83 M4 | PFR5-4024 front bushes | PFR5-4026 rear bush |
Front and rear in this table describe mounting positions on the rear differential, not front-axle differential mounts or rear subframe bushes. A shared rear bush does not establish that a bracket or complete kit fits both generations.
Choose your F8x dual differential bracket package
- PFR5-4030 bracket only: no mounting bushes included.
- Bracket with front mounting bush set: PFR5-4030 plus PFR5-4025; rear bushes are separate.
- Bracket with Genuine BMW rear bushes: PFR5-4030 plus two 33177852495 rubber bushes; no front bush set.
- Complete polyurethane differential mounting kit: PFR5-4030 bracket, PFR5-4025 front set and two PFR5-4026 rear bushes.
G8x dual-bracket enquiries: Powerflex's published PFR5-4030 application list is F8x-specific. Check a proposed G-series bracket against its own manufacturer application before ordering; the common PFR5-4026 rear bush is not proof of bracket interchangeability.
Choosing Road Series, Black Series and the correct bush position
Road Series and Black Series are different product specifications. Black Series is intended for track and motorsport applications; choose by the exact part number rather than appearance alone. Firmer mountings can alter noise and vibration, so a full track-oriented bush package is not automatically the right choice for every road car.
Suspension control-arm bushes, radius-arm bushes, subframe bushes and differential bushes perform different jobs. A full replacement bush is also different from an insert that supports an existing bush. Read each product's position, original component references and installation requirements before purchase.
Use the vehicle selector and filters to narrow the products below, then confirm the individual listing against the car's chassis, drivetrain and existing components. Modified cars require an individual check; there is no blanket fitment guarantee.
