Bilstein 24-187077 Suspension Shock Absorber - Front

Bilstein B8 5100 Front Shock Absorber

The Bilstein B8 5100 shock absorber is a direct-fit suspension upgrade for lifted trucks and SUVs that need controlled front-end damping. Built for vehicles with 3-4 inch front lift applications, this Bilstein shock absorber uses a monotube design and application-specific valving to deliver consistent ride control on and off the road.

Part number 24-187077 is engineered for front suspension use on classic Chevrolet and GMC 4x4 platforms, including Chevrolet K5 Blazer, GMC Jimmy, and full-size Suburban and K-series truck applications. If you are replacing worn front shocks on a lifted Chevrolet Blazer or GMC Jimmy, 24-187077 is built to match the required extended travel and mounting style.

Product Details

The B8 5100 line is tuned for specific vehicle applications, which helps the shock absorber work with the suspension geometry of lifted trucks and SUVs rather than against it. For front suspension service on Chevrolet K10, K20, K30, K5 Blazer, GMC K1500, K2500, K3500, and related Suburban models, this shock is sized to support the added travel common in 3-4 inch lift setups. Bilstein 24-187077 is also cross-referenced to BE5-E655 and F4-BE5-E655-H0 for the same application.

What It Helps Address

• Excessive front-end bounce after hitting bumps or dips
• Reduced control on lifted Chevrolet and GMC 4x4 suspension setups
• Harsh or unsettled ride quality from worn front shocks
• Inconsistent damping during repeated road impacts
• Front suspension travel mismatch on 3-4 inch lift applications

Installation Notes

Compatible With front-position applications only. Confirm lift height, mounting style, and compressed/extended length before installation.
