Bilstein 25-311426 Suspension Shock Absorber - Rear

Bilstein B8 5160 Rear Shock for Titan

The Bilstein B8 5160 remote reservoir shock absorber is a direct-fit rear suspension upgrade for lifted trucks and SUVs. This application is built for the 2017-2024 Nissan TITAN rear with 0-1.5" rear lift, and it uses a monotube design with velocity-sensitive digressive valving for consistent damping on and off the road.

Part number 25-311426 is part of the B8 5160 line, Bilstein’s remote reservoir shock family for lifted applications. The reservoir adds cooling capacity and additional wheel travel, while the 360-degree swivel banjo hose fitting and billet reservoir clamp help support a clean, low-profile installation where applicable.

• Monotube internal design for fade-resistant damping consistency
• Velocity-sensitive digressive valving tuned for the application
• 46mm piston diameter and 14mm shaft diameter
• Zinc-plated finish for added corrosion resistance
• Eye 14mm upper and lower mounts
• Billet reservoir clamp included

Detailed Product Overview

Bilstein 25-311426 is engineered as a rear shock absorber for the Nissan TITAN when equipped with a 0-1.5" rear lift. The smooth-body, non-coilover construction uses a 46mm piston and 14mm shaft to deliver controlled suspension movement, while the remote reservoir helps manage heat during repeated compression cycles. This makes the shock a strong match for towing, uneven terrain, and off-road use where suspension temperatures can rise quickly.

The B8 5160 series focuses on lifted-truck fitment and performance consistency. For shoppers comparing Nissan TITAN rear shock options, part number 25-311426 provides a direct-fit solution with the reservoir-mounted design already matched to the application. This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

Common Issues This Shock Can Address

• Excessive rear-end bounce after a lift installation
• Reduced damping control on rough roads or trails
• Heat-related fade during repeated suspension cycling
• Unstable rear suspension response under load
• Worn or leaking factory-style rear shock absorbers

Installation Notes and Tips

Compatible With 2017-2024 Nissan TITAN rear applications that have 0-1.5" of rear lift. Confirm upper and lower eye mount dimensions before installation, and verify available clearance for the remote reservoir and hose routing. Because this shock is non-adjustable, damping is set by the application-specific valving.

Part number 25-311426 is designed for direct-fit replacement use on the rear suspension. Check ride height and lift configuration before ordering to ensure the vehicle matches the listed fitment.

Quality Assurance

Bilstein’s B8 5160 series uses a monotube shock design, application-specific digressive valving, and a remote reservoir layout to support consistent performance in demanding truck and SUV use. The zinc-plated finish and billet reservoir clamp add durability-focused construction details for long-term service.
