Restore crisp suspension control and protect your shocks with this factory BMW front suspension compression stop, part number 31336859768 (31 33 6 859 768). Designed for F20, F21, F22 and F23 models including M135i, M140i, M235i and M240i, it’s the correct front axle buffer that cushions full-compression impacts, helping to maintain predictable handling, comfort and steering feel on fast road or daily use.
