Bilstein B3 37-161255 Front Suspension Spring for BMW 3 Series E90 E91 E93

Bring your BMW back to its proper stance and comfort with the Bilstein B3 front helical spring, part number 37-161255 (also referenced as BILSTEIN-37-161255). This stock-height front suspension spring is engineered to factory specification for the E90 Saloon, E91 Touring and E93 Convertible, covering diesel and petrol variants including 330d, 335d, 335i and 325d. Ideal when your original spring has snapped, sagged or is causing uneven ride height, this direct-fit unit restores precise steering response and stability without harshness.

Why this Bilstein B3 spring is the smart choice

• Built to original specification for a seamless front-end refresh - retains factory geometry and ride height.
• Precision-formed helical design with model-specific ends for an exact seat in the spring perch - no guesswork.
• Premium spring steel for outstanding strength and longevity - resists breakage and fatigue.
• Heat treated and hot-set to minimise height loss over time - maintains correct nose height and alignment.
• Protective coating for corrosion resistance - helps combat winter salt and UK road grime.
• Trusted Bilstein quality - the go-to choice for OEM-standard replacement suspension on BMW platforms.

We use these on customer cars and the feedback is consistently excellent: smoother ride, confident turn-in and a proper factory look once more. If your 3 Series has failed an MOT for a broken spring or you are refreshing the front end, this Bilstein B3 unit delivers dependable, like-for-like performance.
