Bilstein B8 5160 Front Shock Absorber — 25-312027
Remote reservoir monotube shock for lifted LML and L5P Duramax trucks
Upgrade the front suspension on your lifted 2011–2026 Chevy Silverado or GMC Sierra 2500HD/3500HD with the Bilstein B8 5160 Series shock absorber, part number 25-312027. Built for 2WD and 4WD trucks with 4–6 inches of front lift, this shock is a proven choice for LML and L5P Duramax owners who need more control, cooler operation, and extra wheel travel than a stock-length shock can deliver.
The 5160 uses a 46mm monotube body and a remote reservoir that increases oil capacity for better heat dissipation and more consistent damping on long hauls, work sites, and rough roads. Velocity-sensitive digressive valving is tuned for these heavy-duty GM chassis—firm when the surface gets aggressive, composed and comfortable on the highway. A 360-degree swivel banjo hose fitting keeps the reservoir hose low-profile and easy to route without interference.
Key features
- Remote reservoir for extra oil volume, cooler running, and increased wheel travel
- 46mm monotube design that resists fade compared with twin-tube shocks
- Application-tuned digressive valving for GM 2500/3500 HD geometry
- Zinc-plated body with clear coat for corrosion resistance
- Direct-fit stock mounts (bar-pin upper, clevis lower)—no cutting or welding
- Sold individually (order two for a complete front pair)
