Powerflex Differential Rear Mounting Bush (E46 non-M)
£36.54 – £40.14
The E46’s differential mounting bushes are a known point for excessive deflection and periodic failure. Powerflex developed this polyurethane replacement, available in either standard Powerflex material or harder ‘Black Series’ material, intended for track use. This minimises differential movement, resulting in more consistent power delivery and response while offering compliance for road and track comfort.
Part number 26 on diagram, fits all E46 variants excluding M3. Priced per bush – one pair required per vehicle. Covered under Powerflex’s lifetime warranty.
