Bilstein B8 5100 Series Rear Anti-Wrap Power Hop Shock — Ram 2500 2014–2025
Part No. 24-274395

Upgrade the factory rear axle damper on your Ram 2500 with the Bilstein B8 5100 Series shock absorber 24-274395. This is the dedicated rear axle anti-wrap / power hop shock—not a standard front or rear ride shock. It helps keep the axle planted under hard acceleration, towing, and rough-road use so the truck stays more composed and the drivetrain takes less abuse.

Why this shock

Ram 2500 trucks can suffer rear axle wrap and power hop when torque loads the axle. This monotube damper is application-tuned to control that motion. Bilstein’s 46mm digressive piston and velocity-sensitive valving react as conditions change, delivering consistent, fade-resistant damping instead of the mushy or faded feel of a worn OEM unit.

You get:

• Firmer axle control and less hop under load
• Better stability on washboard, ruts, and uneven pavement
• Improved confidence when towing or launching from a stop
• Direct-fit replacement for the factory power-hop damper

• B8 5100 Series monotube design for consistent, fade-free performance

Important notes

• This damper is only for the rear axle anti-wrap / power hop system. It does not replace the main front or rear suspension shocks.
• If your truck did not come from the factory with the power-hop shock, you will typically need the mounting bracket and hardware in addition to this unit.
• Not intended for air-ride equipped trucks unless confirmed compatible.
• Professional installation recommended. After install, check related suspension fasteners and alignment as needed.

Replace a tired factory damper and put a purpose-built Bilstein monotube on the axle that actually fights wrap and hop.
