$152.99
The original oil-filled differential rear bushing on BMW’s F87 M2, F87 M2C/M2CS, F80 M3 and F82/F83 M4 models is a known point of failure especially when running increased horsepower. Powerflex developed this polyurethane replacement, available in either standard Powerflex material or harder ‘Black Series’ material, intended for track use. This minimises differential deflection, delivering more consistent power delivery and response while offering compliance for road and track comfort. Part number 22 on diagram. Replaces BMW part number 3317785295. Priced per bush – one required per vehicle. Covered under Powerflex’s lifetime warranty.
