Bilstein 25-311792 Suspension Shock Absorber - Front

Bilstein B8 5160 Remote Reservoir Shock

The Bilstein B8 5160 remote reservoir shock absorber is a direct-fit suspension upgrade for lifted Ford Super Duty trucks. Built for front-end applications, it adds cooling capacity and wheel travel to help maintain consistent damping on rough roads and off-road terrain.

Part number 25-311792 is engineered for Ford F-250 Super Duty and Ford F-350 Super Duty front suspension setups with lift-specific fitment.

Key Features

• Monotube internal design for consistent, fade-resistant performance
• Remote reservoir increases fluid capacity and cooling
• Velocity-sensitive digressive valving tuned for the application
• Non-adjustable damping for straightforward operation
• Zinc-plated finish for added corrosion resistance
• 46mm piston with 14mm shaft diameter
• Billet reservoir clamp included where applicable
• 360-degree swivel banjo hose fitting for cleaner routing

Product Line Details

The Bilstein B8 5160 line is built for lifted trucks and SUVs that need more control than a standard shock can provide. This series uses a remote reservoir layout to improve heat management and suspension response, making it a strong match for heavy-duty front suspension use on Ford Super Duty trucks.

Detailed Description

Bilstein 25-311792 is a smooth-body, non-coilover shock absorber with a stem upper mount and 14.4mm eye lower mount. It measures 13.17 inches collapsed, 21.01 inches extended, and provides 7.84 inches of stroke. The monotube construction and digressive valve settings are designed to deliver stable damping across changing road conditions, while the remote reservoir helps manage heat during extended use. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive shock fade during repeated off-road use
• Reduced control on lifted front suspension setups
• Heat buildup in demanding towing or trail conditions
• Harsh ride response from worn front shocks
• Loss of suspension travel after lift installation
