Bilstein 25-311785 Suspension Shock Absorber - Rear

Overview

Bilstein B8 5160 remote reservoir shock absorber 25-311785 is a direct-fit suspension upgrade for lifted trucks and SUVs. It is built for rear applications on select Ford Super Duty models with 0-2 inch rear lift, using a monotube design and remote reservoir layout for more consistent performance under demanding use.

Key Features

• Remote reservoir design increases cooling capacity and wheel travel.
• Monotube internal design supports consistent fade-resistant damping.
• Velocity-sensitive digressive valving is tuned for the application.
• Zinc-plated finish adds corrosion resistance.
• Billet reservoir clamp is included where applicable.
• Non-adjustable damping with smooth-body construction.

Detailed Description

The Bilstein B8 5160 series is engineered for drivers who need controlled suspension response in lifted truck use. Part number 25-311785 uses a 46mm piston, 14mm shaft, and a remote reservoir to help manage heat and maintain damping consistency during rough-road and off-road driving. The eye-to-eye mounting configuration and direct-fit design make it a practical replacement for compatible Ford F-250 Super Duty and Ford F-350 Super Duty rear shock applications.

As part of the B8 5160 line, this shock absorber focuses on durability, thermal management, and application-specific tuning. The 360-degree swivel banjo hose fitting and low-profile reservoir mount help support a clean installation where space is limited. For buyers searching for a Ford F-250 Super Duty rear shock absorber or Ford F-350 Super Duty rear shock absorber, 25-311785 matches the lifted-truck use case with the B8 5160 platform.

What It Is Used For

• Rear suspension control on lifted Ford Super Duty trucks.
• Reducing fade during repeated rough-terrain use.
• Improving wheel travel in 0-2 inch rear lift setups.
• Replacing worn shocks that no longer control rebound and compression properly.
• Supporting more stable damping in off-road conditions.

Installation Notes

Fits 2005-2016 Ford F-250 Super Duty, rear. Fits 2005-2016 Ford F-350 Super Duty, rear. Confirm rear lift height and mounting style before installation. This part cross-references Monroe Shocks & Struts (e.g., 985-24-104, BR5-H076) for the same application.

Quality Assurance

Bilstein B8 5160 shocks use a monotube architecture and application-specific valving to support consistent damping performance. Part number 25-311785 is part of Bilstein’s B8 5160 series for lifted truck suspension applications.
