Bilstein 25-311907 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 trucks and SUVs that need more control on rough terrain. This front shock is engineered for the 2014-2025 Ram 2500 with a 2-2.5 inch front lift and uses a monotube design for consistent damping response.

Part number 25-311907 is built for drivers who want improved cooling capacity, added wheel travel, and a cleaner installation layout on a lifted Ram 2500 front suspension.

Bilstein B8 5160 Series Details

The Bilstein B8 5160 line is designed for lifted light trucks and SUVs that need more thermal capacity and suspension control than a standard shock absorber can provide. This series uses a remote reservoir layout to help manage heat during repeated compression and rebound cycles, while the monotube construction supports stable damping response across demanding off-road conditions. Part number 25-311907 follows that formula for Ram 2500 front applications.

This part cross-references Bilstein 25-240429 for the same application.

What It Helps Address

• Excessive shock fade during extended off-road driving
• Reduced front suspension control on lifted Ram 2500 trucks
• Heat buildup from repeated compression over rough surfaces
• Limited wheel travel from a standard shock setup
• Loose or unsettled front-end feel on uneven terrain

Installation Notes

Fits 2014-2025 Ram 2500, front, with 2-2.5 inch front lift. Verify lift height, mount style, and available clearance before installation. The remote reservoir and hose routing should be positioned to avoid contact with moving suspension components, tires, and steering parts. Professional installation is recommended for lifted suspension systems.

Quality Assurance

Bilstein designs the B8 5160 series for light truck use with application-specific valving, monotube construction, and a remote reservoir layout intended to support durability in harsh off-road environments. Part number 25-311907 is built to Bilstein’s suspension standards for the Ram 2500 front application.
