OEM-Spec Rear Suspension Spring | Bilstein B3 | Part No. 36-301089 | For BMW X5 E70 2006 to 2013

Bring your E70 back to its best with this factory-quality back suspension coil. Built in the Bilstein B3 line and matched to original equipment standards, part number 36-301089 restores correct ride height, confidence-inspiring stability and the smooth, quiet composure you expect from a well-sorted BMW SUV.

We have installed this spring on customer vehicles in our own workshop and the results speak for themselves. Owners report a level stance, improved comfort over bumps and a tighter, more controlled rear end under load. If your X5 feels low at the back, crashes over rough roads or has failed an MOT for a tired spring, this is the quality solution.

Why choose this B3 rear spring

• Direct swap for the rear position on the E70 chassis for selected AWD petrol and diesel models.
• Returns stock height and factory handling without harshness.
• Correct OE-style winding and end profiles for perfect seating and quiet operation.
• Premium spring steel with excellent fatigue resistance for long service life.
• Hot-set and shot-peened to minimise settling and resist breakage.
• Durable protective coating for corrosion resistance on UK roads.
• Ideal for suspension refresh, MOT prep and fixing a sagging rear corner.
• Trusted Bilstein quality that matches original equipment performance.
