Product Description

The Bilstein B8 5160 25-311785 is a rear remote reservoir shock absorber engineered for the 2005-2016 Ford F-250 and F-350 Super Duty 4WD, covering the full range of trims, cab styles, bed lengths, and engine options across both the 3rd and 4th generation Super Duty platforms. Built on a 46mm monotube body with self-adjusting deflective disc valving, it delivers controlled, fade-free damping tuned to match the weight and demands of a heavy-duty truck - whether it's loaded, towing, or running off-road with up to 2 inches of rear lift.

The remote reservoir significantly expands oil volume and heat dissipation capacity compared to standard shocks, keeping performance stable under the sustained stress that Super Duty owners regularly put these trucks through. Installation is a straightforward bolt-on at factory mounting locations across all SRW and DRW F-350 configurations, with no cutting or fabrication needed. It's a race-derived solution that drops directly into a working truck.
