Bilstein B8 5100 Series Shock Absorber – 24-285674
Front | 4" Lift | 2014–2026 Ram 2500 4WD & 2013–2026 Ram 3500 4WD
Upgrade your lifted Ram with the shock built for the extra travel, larger tires, and heavier loads that stock dampers weren’t designed to handle. The Bilstein B8 5100 (24-285674) is a vehicle-specific monotube shock for the front of 4WD Ram 2500/3500 trucks with a 4" front lift. It delivers firmer control without turning everyday driving into a harsh ride.
Why it works
Lifted heavy-duty Rams put more demand on the suspension. Bilstein’s 46mm monotube design, high-pressure nitrogen charge, and patented velocity-sensitive digressive piston react instantly to changing surfaces—highway, washboard, loaded towing, or light off-road—so the truck stays planted and fade-free. Each unit is tuned for this application rather than using generic valving.
Key features
- 46mm monotube gas-pressure design for consistent, fade-free damping and better heat dissipation than twin-tube shocks
- Velocity-sensitive digressive piston that adjusts to road inputs in real time
- Application-specific valving for 4" lifted Ram 2500/3500 4WD
- Zinc-plated body for corrosion resistance
- Black bellows boot and OEM-style hardware for a direct bolt-on install
- Smooth-body (non-coilover) construction
- Made in the USA
- Limited lifetime warranty
Fitment
- Position: Front (driver or passenger; sold individually — order 2 for a pair)
- Drive: 4WD only
- Lift: Designed for 4" front lift
- Vehicles: 2014–2026 Ram 2500 4WD • 2013–2026 Ram 3500 4WD
Important: Manufacturer lift height is a guideline. Aftermarket kits vary. Measure your shock: pin-to-eye from the base of the stem (where hardware seats) to the center of the lower eye. Confirm collapsed/extended length before ordering.
