Bilstein 25-316957 Suspension Shock Absorber - Rear

Bilstein B8 5160 Rear Shock Absorber

The Bilstein B8 5160 remote reservoir shock absorber is a direct-fit upgrade for lifted trucks and SUVs that need more control at the rear suspension. This rear shock for Chevrolet Silverado 1500 and GMC Sierra 1500 applications uses a monotube design, a 46mm piston, and a remote reservoir to support consistent damping and added cooling capacity.

Key Features

• Direct-fit rear shock absorber for lifted truck and SUV applications
• Remote reservoir design increases cooling capacity and wheel travel
• Monotube internal design for consistent fade-free performance
• Velocity-sensitive digressive valving tuned for the specific application
• Non-adjustable damping for straightforward setup
• Zinc-plated finish for added corrosion resistance
• Billet reservoir clamp included
• 360-degree swivel banjo hose fitting for cleaner routing
• 46mm piston and 14mm shaft diameter

Product Details

Bilstein B8 5160, part number 25-316957, is built for rear suspension use on 2019-2025 Chevrolet Silverado 1500 and 2019-2025 GMC Sierra 1500 models with 0-1 inch rear lift, plus 2022 Chevrolet Silverado 1500 LTD and 2022 GMC Sierra 1500 Limited rear applications. The B8 5160 line focuses on remote reservoir performance, giving the shock more thermal capacity than a traditional non-reservoir design while maintaining a low-profile installation with the included billet reservoir mount where applicable. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Uses

• Rear-end bounce or instability after a lift
• Excess heat buildup during rough-road or off-road driving
• Reduced wheel travel from worn factory-style shocks
• Inconsistent damping over repeated suspension cycles
• Need for a direct-fit rear shock upgrade on Silverado 1500 or Sierra 1500 trucks

Installation Notes

Install in the rear position only. Confirm your truck has 0-1 inch of rear lift before ordering, and verify upper and lower eye mounts measure 14.1mm. The shock has a collapsed length of 15.51 inches, an extended length of 26.01 inches, and 10.50 inches of stroke, so suspension travel and mounting clearance should be checked during installation. No boot is included.

Quality Assurance

Bilstein B8 5160 shocks use a monotube construction, digressive valving, and a remote reservoir layout to support stable damping performance under demanding use. Part number 25-316957 is engineered for the listed rear-fit Silverado 1500 and Sierra 1500 applications.
