Product Description

The Bilstein 25-316919 B8 5160 rear right shock absorber is a premium performance replacement designed specifically for lifted Dodge Ram 1500 4WD trucks. Unlike standard shocks, this 5160 series unit features a remote reservoir that greatly increases oil capacity for superior heat dissipation and sustained performance on rough terrain. Built with a 46 mm gas-charged monotube design and velocity-sensitive digressive valving tuned for Ram applications, this shock delivers improved wheel control, enhanced stability, and reduced fade under heavy use - whether towing, hauling, or off-roading.

Engineered as a direct bolt-in replacement for the rear right position on 2019-2025 Ram 1500 4WD models without factory air suspension, the 25-316919 helps maintain consistent damping and articulation at ride heights with a 0-2" rear lift. Its zinc-plated finish and 360° swivel banjo reservoir fitting provide corrosion resistance and a clean installation. For best results and balanced performance, install this shock in pairs with the matching left side unit.
