Bilstein B8 5160 Rear Shock Absorber — 25-302349
For 2013–2025 Ram 3500 4WD | Remote Reservoir | Sold Individually
Upgrade the rear of your 2013–2025 Ram 3500 with a bolt-on Bilstein B8 5160 remote-reservoir shock built for work, towing, and off-road use. Part number 25-302349 uses a 46 mm monotube design and an external reservoir so the shock stays cooler and more consistent when the truck is loaded, on washboard roads, or on the trail.
This is a rear, single shock. Most trucks need two. It is intended for 4WD Ram 3500 models without factory air-leveling or air-ride suspension, typically with stock to about 0–1" of rear lift. Some catalogs list up to 0–3" rear lift. Confirm lift height, drivetrain, and suspension type before ordering.
Why it belongs on the truck
The B8 5160 is not a stock-replacement twin-tube. The remote reservoir adds oil volume and heat capacity, which helps reduce fade on long grades, heavy payloads, and repeated hits. Velocity-sensitive digressive valving is application-tuned so the shock can stay composed over small chatter and still control big compression events. A 360° swivel banjo hose fitting and included billet reservoir clamp keep the install clean and low-profile on the frame.
Zinc-plated body, 14 mm shaft, and eye-to-eye 14.1 mm mounts are built for a direct fit in the factory rear locations. Made in the USA.
