Bilstein 19-145266 B4 Rear Damper for BMW E93 Cabriolet

Bring your BMW 3 Series E93 Cabriolet back to its best with the Bilstein B4 rear damper, part number 19-145266. This single rear unit is built to original equipment standards with twin tube, gas pressurised technology for consistent control, confident road holding and the comfort your BMW was designed to deliver. Ideal when your back shock is tired, leaking or knocking, it is a straight swap that restores the stock ride without harshness.

We fit these B4 units regularly on customer E93 cabriolets and the feedback is always the same: smoother ride, tighter rear end stability and dependable quality. If you want a factory-spec replacement that simply works, this is the go-to rear shocker for the E93 chassis.
