Bilstein B8 5160 Series Remote Reservoir Rear Shock Absorber (25-311846)
Upgrade the rear suspension on your lifted Duramax with the Bilstein B8 5160 Series remote reservoir shock absorber. Engineered as a direct-fit solution for 2001–2026 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks (2WD and 4WD), this monotube shock delivers superior control, increased wheel travel, and fade-free performance under heavy loads, towing, and off-road use.
Why the B8 5160 Stands Out
The remote reservoir significantly increases oil capacity and cooling, helping the shock stay consistent during extended highway runs, towing, or trail abuse. Bilstein’s velocity-sensitive digressive valving reacts instantly to changing terrain, providing firm control over larger tires and added ride height while maintaining a more comfortable on-road feel than many conventional shocks. The 46 mm monotube design and zinc-plated finish deliver the durability expected from Bilstein in harsh environments.
Key Features
- Remote reservoir for greater oil capacity and heat dissipation
- Monotube construction for consistent, fade-resistant damping
- Application-specific digressive piston valving
- 360° swivel banjo fitting for clean, low-profile hose routing
- Billet reservoir clamp included
- Zinc-plated body for corrosion resistance
- Smooth-body (non-coilover) design
- Sold individually (pair required for both rear corners)
Specifications
- Part Number: 25-311846

Fitment note: Designed for 3–4″ rear lift applications on 2001–2026 GM 2500/3500HD trucks. Because aftermarket lift kits vary, verify collapsed and extended lengths against your current setup before ordering. Compatible with both 2WD and 4WD configurations.
Whether you’re daily-driving a work truck, towing a trailer, or hitting the trails, the Bilstein 25-311846 B8 5160 rear shock gives your lifted Duramax the damping capacity and control it needs.
