Bilstein 25-311273 Suspension Shock Absorber - Rear

Bilstein B8 5160 Rear Shock

The Bilstein B8 5160 remote reservoir shock absorber is a direct-fit suspension upgrade for lifted trucks and SUVs. It is built for applications that need more cooling capacity, more wheel travel, and consistent damping under demanding off-road use.

Key Features

• Remote reservoir design increases cooling capacity and helps maintain performance during extended use.
• Monotube internal design delivers consistent, fade-resistant damping.
• Velocity-sensitive digressive valving is tuned for the specific application.
• Zinc-plated finish adds corrosion resistance.
• Includes a billet reservoir clamp and a 360-degree swivel banjo hose fitting where applicable.
• Non-adjustable damping with a smooth-body, non-coilover construction.

Detailed Description

This Bilstein shock absorber is part of the B8 5160 line, a remote reservoir series engineered for lifted light trucks. The reservoir separates fluid volume from the main body to improve heat management, while the monotube layout and 46 mm piston support stable response over rough terrain. Part number 25-311273 is listed for the rear of 2000-2006 Toyota Tundra with 0-2 inch rear lift, making it a fitment-specific replacement for that application. If you are searching for a Toyota Tundra rear shock absorber or a Bilstein 25-311273 replacement, this unit matches the listed configuration.

This part cross-references Bilstein (e.g., 25-261332, 25-243734) for the same application.

What It Is Used For

• Replacing a worn rear shock on a lifted Toyota Tundra.
• Reducing fade during repeated suspension movement.
• Improving control on rough roads and off-road terrain.
• Restoring proper damping response after shock wear.
• Supporting rear suspension travel in lift-specific applications.

Installation Notes and Tips

Fits 2000-2006 Toyota Tundra, rear. Confirm rear lift height is 0-2 inches before ordering. Verify upper stem and lower eye 12 mm mount points against the existing shock before installation. Part number 25-311273 should be matched to the listed fitment only.

Quality Assurance

Bilstein B8 5160 shocks use a monotube design, digressive valving, and a remote reservoir layout to support consistent performance in demanding service.
