Bilstein B3 Front Suspension Spring - Reference 37-313449 - BMW 3 Series E90 E91 E92 AWD

Bring your BMW back to its crisp, factory-feel with this genuine Bilstein B3 front suspension spring. Part number 37-313449, also listed as BILSTEIN-37-313449, is designed for the all-wheel drive E9x platform and restores correct ride height, consistent steering response and everyday comfort without compromise.

At MJ Modifications we have installed these on customer cars and our own builds, and the results speak for themselves. Tired, sagging or cracked road springs ruin handling and tyre wear. Swap to this Bilstein B3 unit on the front position and enjoy precise control, quiet operation and an OE-quality finish that lasts.
