Detailed Description

Bilstein B6 Performance dampers are engineered as an OE spring pairing upgrade, giving the suspension more controlled movement without changing the factory spring setup. On the 1990-1991 Chevrolet Corvette, rear, with Selective Ride, this shock absorber is built to improve handling stability, braking control, and overall suspension response. The monotube construction helps maintain damping consistency under repeated use, while the valving is matched to the application for a more direct driving feel. Part number 20-070014 is also referenced for this rear Corvette application.

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

What It Helps Address

• Excessive rear suspension bounce or oscillation
• Reduced cornering control on a 1990-1991 Chevrolet Corvette
• Soft or inconsistent damping from worn OE shocks
• Unstable ride quality during braking or lane changes
• Loss of rear-end composure with Selective Ride-equipped suspension

Installation Notes
