Bilstein B3 Rear Suspension Spring 38-129223 for BMW 3-Series E46

Restore the stance, comfort and stability of your E46 with this Bilstein B3 rear suspension spring. Engineered to factory specification for selected BMW 3-Series E46 petrol models, it returns the car to the correct standard ride height with the precise control and quiet operation you expect from Bilstein. Ideal when your original back spring is tired, cracked or the rear end is sitting low.

We have installed this part in our own workshop for many customer cars and the feedback has been excellent. Customers report a planted rear end, consistent ride height and a smooth, controlled feel on British roads and motorways.

Why this spring is the right choice

• Factory-spec spring rate and geometry for stock-height E46 handling and comfort
• High-grade spring steel with durable anti-corrosion finish for long service life
• Hot-set manufacturing to resist height loss and sag over time
• Precise fit on the back axle for quick, hassle-free installation
• Perfect for replacing broken rear coils or resolving uneven ride height
