Product Details

Bilstein B8 5100 shocks are built for rear suspension applications where lift height changes the factory shock geometry. This shock absorber uses a monotube construction and a digressive piston profile to respond to road inputs with stable control and predictable damping. The application-specific tuning helps maintain ride quality and handling on lifted Chevrolet and GMC platforms, including rear shock replacement for 1973-1991 Chevrolet Blazer, K5 Blazer, K10, K20, Suburban models, and GMC Jimmy, K1500, K2500, and Suburban variants.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Bilstein part number 24-187084 is also referenced by interchange numbers BE5-E656, F4-BE5-E656-H0, and RS77112.

Common Issues This Shock Can Address

• Excessive rear bounce after a suspension lift
• Reduced control over rough pavement and washboard roads
• Harsh or inconsistent rear ride quality
• Rear-end instability during cornering or braking
• Loss of damping performance from worn factory-style shocks
