Bilstein 24-139380 Suspension Shock Absorber - Rear Left
Bilstein B6 Rear Left Shock for Mini Cooper
The Bilstein B6 Performance shock absorber, part number 24-139380, is a direct suspension upgrade for OE factory spring setups. It is built for the rear left position on select Mini Cooper models and uses a monotube design with application-specific valving to improve handling response and road control.
Compatible With 2007-2015 Mini Cooper, rear left, this Bilstein shock absorber is engineered for drivers who want firmer damping and more consistent suspension behavior without changing the factory spring package. The yellow-painted B6 Performance finish identifies the line and helps distinguish it from standard replacement dampers.

Product Details
The B6 Performance line is Bilstein’s performance-oriented damper range for vehicles retaining the original factory spring. For the Mini Cooper, this shock absorber is tuned to improve handling stability, steering feel, and overall suspension control while maintaining OE-style spring compatibility. Each unit is tested to meet or exceed OE standards, making it a practical choice for restoring damping performance on higher-mileage suspension systems or upgrading from a worn factory shock. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

- Excessive bouncing or poor rebound control from a worn rear shock
