Bilstein B3 Rear Coil Spring 36-313235 for BMW 3 Series E90 Saloon E93 Convertible - OE Spec Rear Axle Replacement, Stock Height, Direct Fit

Bilstein B3 36-313235 Rear Suspension Spring for BMW 3 Series E90 and E93

Get your BMW riding as it should with the Bilstein B3 rear suspension coil, part number 36-313235. This genuine Bilstein component is built to the same specification as the factory spring to bring back original comfort, stability and confidence. It is a direct bolt-on for the back axle on BMW 3 Series E90 Saloon and E93 Convertible models, maintaining standard ride height and stock handling feel without compromise.

What makes it a smart upgrade

• OEM-level fit and geometry for the correct rear stance and alignment
• Manufactured from high-strength chrome vanadium or chrome silicon steel for durability and crack resistance
• Engineered end shapes including pigtail and minibloc designs for precise, quiet spring action
• Hot set during production to minimise height loss over time
• Surface compressed and coated for excellent corrosion protection and long service life
• Restores the planted, composed feel you expect from a well-sorted BMW chassis

We have installed this Bilstein B3 on customer cars and on our own builds. Feedback has been consistently positive, with owners praising the factory-fresh ride quality, improved rear-end control and the way it eliminates the sag or uneven stance caused by tired or broken springs.
