Description
Strongflex BMW E46 eccentric control arm bush 66 mm (front axle) – 031518B
The Strongflex 031518B Front lower control arm bush 66mm – eccentric is a polyurethane control arm bush for the front axle of the BMW E46. This version, with a hardness of 80ShA, replaces the soft, wear-prone original rubber and delivers sharper handling, less play and more direct steering.
The control arm bushes determine how precisely the front wheels are located. With PU bushes the geometry stays stable under high loads: sharper steering and better braking.
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.
