Bilstein 25-312164 Suspension Shock Absorber - Front Right

Bilstein B8 5160 Remote Reservoir Shock

The Bilstein B8 5160 remote reservoir shock absorber is a direct-fit suspension upgrade for lifted trucks and SUVs that need more control on rough terrain. This front right shock is engineered for select Mercedes-Benz G550, G55 AMG, and G500 applications, including vehicles with 0-2 inch front lift where specified.

Built around Bilstein’s B8 5160 line, this shock uses a monotube design and velocity-sensitive digressive valving to deliver consistent damping response. The remote reservoir adds cooling capacity and additional wheel travel, while the zinc-plated finish and 360-degree swivel banjo hose fitting support a clean, low-profile installation.

B8 5160 Product Line Details

The Bilstein B8 5160 series is designed for lifted light trucks and SUVs that need improved suspension control without changing the factory-style shock layout. The remote reservoir helps manage heat during repeated compression and rebound cycles, which is important for off-road driving, uneven pavement, and heavier front-end loads. This part number, 25-312164, follows that formula with a direct-fit configuration for the front right position.

Fitment

• Fits 2016-2018 Mercedes-Benz G550, front right, without electronic suspension; B8 5160

What this shock absorber helps address:

• Excessive fade during repeated off-road suspension movement
• Reduced damping control on lifted front suspension setups
• Heat buildup from demanding trail or rough-road use
• Loss of wheel travel and suspension response under load
• Need for a direct-fit front right replacement on supported Mercedes-Benz models
