Bilstein B8 5100 Series Rear Shock Absorber — 24-285698
For 2014–2025 Ram 2500 4WD with a 4" rear lift (no air leveling)
Give a lifted Ram 2500 the damping it needs when stock shocks run out of travel. The Bilstein B8 5100 (24-285698) is a direct-fit rear monotube shock tuned for 4WD 2500s with about 4 inches of rear lift and coil-spring suspension. It is built for larger tires, extra ride height, and mixed highway and off-road use. It does not fit trucks with rear air leveling.
A 46mm velocity-sensitive digressive piston reacts as the surface changes, so you get control over washboard, ruts, and highway without the fade common to twin-tube shocks. High-pressure monotube construction keeps oil and gas separated for consistent heat control and longer life. The zinc-plated body and black bellows boot stand up to salt, mud, and daily use.
Sold individually. Most trucks need two rear shocks.

Why this shock
Tuned specifically for lifted Ram 2500 rear geometry. Digressive valving delivers comfort at low speed and control at high speed. Cooler, more consistent performance than stock twin-tube shocks. Bolt-on install using factory-style mounts. Replacement hardware kit is Bilstein B4-KT1-Z223A01 if needed. Better composure with larger tires, towing, and trail use.
Notes
Confirm your truck has no rear air leveling and that your measured shock length matches 18.66" collapsed / 28.24" extended before install.
