Description
Strongflex BMW E46 M3 front differential mount bush SPORT (rear axle) – 031898A
The Strongflex 031898A Rear differential – front mount bush M3 SPORT is a polyurethane differential mount bush (M3) for the rear axle of the BMW E46 M3. 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 M3-specific differential mount bushes hold the diff firmly in place. PU reduces diff movement and wheel hop for more direct acceleration and traction.
Compatible with:
- BMW E46 M3 (2000–2006)
Various M3 parts also fit the BMW Z4 M (E85/E86) – always check the Strongflex reference.
