Product Details

Bilstein B6 Performance dampers are engineered as a performance-focused replacement for factory dampers while retaining the OE spring setup. For Porsche 911 rear suspension applications, this shock absorber is tuned to improve handling precision, stability, and safety without changing the original spring configuration. The monotube construction supports more consistent damping performance, and each unit is tested to meet or exceed OE standards. This part number 24-015479 is a direct-fit rear shock absorber for Porsche 911 models from 1991 through 1994.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive rear-end bounce or oscillation
• Reduced cornering stability on a Porsche 911
• Worn factory shock performance
• Inconsistent damping response over rough pavement
• Loss of control feel during braking and lane changes

Installation Notes

Install on the rear position only for 1991-1994 Porsche 911 applications. Verify the lower eye 14mm mount and upper stem mount before installation, and confirm the OE spring remains in use as specified for the B6 Performance line. Inspect related suspension components, including mounts and bushings, before replacing the shock absorber.

Quality Assurance

Bilstein B6 Performance dampers are rigorously tested and built to meet or exceed OE standards. The zinc-plated finish and monotube design reflect Bilstein’s focus on durable, application-specific suspension control for Porsche 911 rear shock replacement applications.
