Bilstein B3 Rear Suspension Spring 38-129087 for BMW 3-Series E36 Rear Position

Bring your E36 back to factory stance and tight road manners with the Bilstein B3 rear suspension spring, part number 38-129087. This OEM-grade helical spring is a direct-fit component for the back axle on BMW 3-Series E36 Saloon and Coupe models, restoring stock ride height, comfort and confident stability. Ideal when a rear spring has snapped, sagged or caused an MOT failure, it is the reliable, long-life solution enthusiasts and technicians trust.

We have installed these on customer E36 builds in our own workshop and the feedback is consistently excellent. Expect crisp handling, quiet operation and a proper factory feel without harshness or unwanted lowering.

Why this spring stands out

• Genuine OEM-level quality from Bilstein for long service life
• Direct-fit to the rear position on the E36 chassis with no modifications
• Restores stock height and geometry for predictable grip and tyre wear
• Premium spring steel with high break resistance for durability
• Hot set after forming to minimise height loss over time
• Shot-peened and coated for corrosion protection in UK conditions
• Correct OE-style ends and shapes for quiet, precise seating
