Bilstein B3 Front Road Spring 37-251338 for BMW F-Series Front Axle

Bring back crisp steering, correct stance and that factory-fresh ride with the Bilstein B3 front suspension spring. This OE-spec helical spring is a direct-fit replacement for a wide range of BMW F-chassis models and engines, including 1 Series F20 F21, 2 Series F22 F23 and 3 Series F30 F31 F34. Perfect for everyday driving and spirited use, it restores the balance, comfort and control your BMW was designed to deliver.

At MJ Modifications we run B3 springs on our own builds and have fitted them for many customers. Feedback is consistently positive: smooth, quiet operation, stock ride height retained and that planted BMW feel you expect. If your original front road spring is cracked, sagging or tired, Bilstein B3 is the reliable, OE-matched answer.

• High-grade spring steel with excellent fatigue strength for long service life
• Hot-set and surface-treated to resist height loss and corrosion
• Precisely formed ends for correct seating and reduced noise
