Bilstein's 25-311891 is a B8 5160 rear shock absorber for 2011-2026 Chevrolet Silverado 2500 HD/Silverado 3500 HD & GMC Sierra 2500 HD/Sierra 3500 HD. It uses Bilstein's monotube construction, which keeps the gas and oil separated so damping stays consistent under sustained use. A remote reservoir adds oil capacity for heat control on rough or loaded use.
Bilstein B8 5160 remote reservoir shock absorbers are designed as a direct fit solution for lifted trucks and SUVs. The remote reservoir will offer increased cooling capacity and wheel travel to optimize overall performance compared to a traditional shock absorber. These shock absorbers feature a monotube design for consistent fade free performance and utilize velocity sensitive digressive valve settings which are tuned for each specific application. Each shock absorber is fitted with a unique 360 degree swivel banjo hose fitting and an attractive billet reservoir mount where applicable providing a clean, low profile installation. B8 5160 remote reservoir shock absorbers will increase overall durability of your vehicle allowing you to conquer the harshest of off-road environments.
