Restore your E46 to factory-spec handling and stance with the Bilstein B3 front suspension coil, part number 36-233250. This direct-fit spring is built to the same high standards as the original BMW item, giving you precise ride height, quiet operation and dependable everyday comfort on UK roads.

Ideal for replacing a tired, cracked or sagging front spring, the B3 range uses premium materials and proven Bilstein manufacturing processes for long service life and consistent performance. We have installed these on our own cars and customer vehicles, and the feedback is always the same, a stock-height E46 that rides properly again and feels tight, composed and confidence inspiring.
