Description
BMW E46 differential front mount bush SPORT (rear axle) BLACK
Strongflex – 031751AX
The Strongflex 031751AX Rear differential front mount bush SPORT is a polyurethane differential mount bush for the rear axle of the BMW E46. This version, with a hardness of 90ShA, replaces the soft, wear-prone original rubber and delivers sharper handling, less play and more direct steering.
The differential mount bushes hold the diff firmly in place. PU bushes reduce diff movement and wheel hop: more direct acceleration and traction.
Compatible with:
- BMW 3 Series E46 (1998–2007) – rear-wheel drive (RWD)
- BMW E46 Compact (2001–2004)
Many of these parts also fit the BMW Z4 (E85/E86) and E36 – always check the Strongflex reference.
