Bilstein 25-311808 Suspension Shock Absorber - Rear
Bilstein B8 5160 Rear Shock for Lifted Super Duty
The Bilstein B8 5160 remote reservoir shock absorber is a direct-fit rear suspension upgrade for lifted Ford F-250 Super Duty and Ford F-350 Super Duty trucks. Part number 25-311808 is built for 0-3 inch rear lift applications and uses a remote reservoir to add cooling capacity and wheel travel for more consistent performance on rough roads and off-road terrain.
Key Features
- Fits 2017-2026 Ford F-250 Super Duty, rear, with 0-3 inch rear lift
- Fits 2017-2026 Ford F-350 Super Duty, rear, with 0-3 inch rear lift
- Bilstein B8 5160 series remote reservoir design
- Monotube internal design for consistent fade-resistant damping
- Velocity-sensitive digressive valving tuned for the application
- 46mm piston diameter and 14mm shaft diameter
- Eye 14mm lower mount and eye 16mm upper mount
- Zinc-plated finish for added corrosion resistance
- Billet reservoir clamp included where applicable
Product Details
Bilstein B8 5160 shocks are engineered for lifted light trucks that need controlled rear suspension movement without sacrificing ride consistency. The remote reservoir helps manage heat during extended use, while the monotube construction supports stable damping response over changing terrain. This part number, 25-311808, is designed for Ford Super Duty rear applications and uses a smooth-body shock layout with a 13.14-inch stroke, 18.50-inch collapsed length, and 31.76-inch extended length.
The B8 5160 line focuses on clean installation and application-specific tuning. On 2017-2026 Ford F-250 Super Duty and 2017-2026 Ford F-350 Super Duty trucks, rear suspension performance can benefit from improved cooling, more usable travel, and consistent control under load or on uneven surfaces. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What This Shock Absorber Helps Address
- Excess rear suspension heat during extended off-road or heavy-use driving
- Reduced damping consistency from standard shocks on lifted trucks
- Rear-end instability over washboard roads, ruts, and uneven terrain
- Limited wheel travel after a 0-3 inch rear lift
- Loss of control and ride quality in Ford Super Duty rear suspension setups
Installation Notes and Tips
Compatible with rear-position applications only. Verify that your truck has a 0-3 inch rear lift before ordering, and confirm upper and lower mount style, collapsed length, and extended length against the vehicle’s suspension geometry. Because this is a remote reservoir shock, plan routing and mounting carefully so the reservoir and hose clear moving suspension components throughout full travel. Part number 25-311808 is intended for direct-fit use on the listed Ford F-250 Super Duty and Ford F-350 Super Duty applications.
Quality Assurance
Bilstein designs the B8 5160 series with a monotube shock body, application-specific digressive valving, and a remote reservoir layout to support durable performance in demanding truck and SUV use. The zinc-plated finish and billet reservoir clamp help support a clean, low-profile installation where applicable.
