Description
The Bilstein B8 5160 remote reservoir shock absorber, part number 25-311839, is engineered as a direct-fit suspension upgrade for lifted light trucks and SUVs. Its remote reservoir increases cooling capacity and supports greater wheel travel than a traditional shock absorber, helping optimize handling and durability during demanding off-road use. This shock is designed for compatible Chevrolet Silverado, Chevrolet Silverado HD, Chevrolet Silverado Classic, Chevrolet Silverado 2500 HD Classic, Chevrolet Silverado 3500 Classic, GMC Sierra, GMC Sierra 2500 HD Classic, and GMC Sierra 3500 applications, including select 2004–2007 models. Verify vehicle fitment before installation.
The 46mm monotube design provides consistent, fade-resistant performance in changing driving conditions. Bilstein velocity-sensitive digressive valving is specifically tuned for the application, delivering controlled suspension response while maintaining reliable performance on pavement, gravel, trails, and rough terrain. A 14mm shaft and zinc-plated finish contribute to long-term durability, while the smooth-body, non-coilover construction provides a straightforward solution for upgraded suspension systems.
This Bilstein B8 5160 shock absorber features a remote reservoir and a unique 360-degree swivel banjo hose fitting for a clean, low-profile installation. The upper stem mount and lower 14.1mm eye mount are designed for the specified applications. With a 9.03-inch stroke and a 22.51-inch extended length, this non-adjustable shock absorber is built to support lifted-truck suspension travel without requiring a spring seat, protective boot, or included billet reservoir clamp. This product may require installation by a qualified technician. California Proposition 65 warning: Cancer and Reproductive Harm—www.P65Warnings.ca.gov.
