• Monotube internal design for consistent fade-resistant performance
• Velocity-sensitive digressive piston for responsive damping
• Non-adjustable damping
• 46mm body diameter
• Zinc-plated finish for corrosion resistance
• Black bellows boot included
• Upper stem mount and lower eye mount, 14.1mm
• Collapsed length: 17.08 in. / Extended length: 26.75 in.

Product Details

The Bilstein B8 5100 line is built for lifted truck and SUV suspension setups that need controlled front-end damping without adjustable settings. This shock absorber is tuned for its specific application, helping maintain ride quality, steering response, and comfort on Ram 2500 and Ram 3500 trucks equipped with a 6-inch front lift. Part number 24-285704 is engineered as a direct-fit replacement for the front position and uses Bilstein’s monotube construction to manage heat and repeated suspension movement more consistently than conventional twin-tube designs.

This part cross-references Monroe Shocks & Struts (e.g., 985-24-203) for the same application.

Compatible Vehicles

• Fits 2014-2025 Ram 2500, front, with 6" front lift; B8 5100
• Fits 2013-2025 Ram 3500, front, with 6" front lift; B8 5100

What It Helps Address

• Excessive front-end bounce after a lift kit installation
• Reduced damping control on rough pavement or uneven roads
• Front suspension instability during towing or hauling
• Harsh ride quality caused by mismatched shock length
• Premature shock fade from repeated suspension cycling

Installation Notes

Verify front lift height before ordering, since this shock is listed for Ram 2500 and Ram 3500 trucks with a 6-inch front lift. Confirm upper stem and lower eye mounting points, along with collapsed and extended length requirements, to ensure proper suspension travel. Professional installation is recommended for lifted heavy-duty truck applications, and the shock should be inspected after installation to confirm full articulation without topping out or binding.

Quality Assurance

Bilstein designs the B8 5100 series as an application-specific suspension shock absorber for lifted trucks and SUVs. The monotube construction, zinc-plated finish, and tuned valving are selected to support consistent front suspension performance in demanding use.
