Take The Bounce Out Of Your Lifted Ram

A lifted truck should inspire confidence, not leave you fighting unwanted suspension movement on every drive. The Bilstein 24-285698 B8 5100 Rear Shock is built specifically for 2014-2026 Ram 2500 4WD models without factory rear air leveling and equipped with a 4 inch lift, giving your suspension the support it needs to perform at its best. Whether you spend your time towing a heavy trailer, traveling back roads, or driving to work every morning, this shock helps keep the rear of the truck stable and controlled. Additionally, the monotube gas pressure design delivers consistent damping that holds up during long trips and demanding conditions where ordinary shocks begin to lose effectiveness. The result is better ride quality, improved confidence through uneven terrain, and a truck that feels more settled when carrying weight. Bilstein's corrosion resistant zinc plated finish is designed to stand up to mud, moisture, and road salt, making it an excellent choice for year round use. It is a suspension upgrade that gives your lifted Ram the balanced ride and dependable performance it deserves.

Built To Complement A Four Inch Lift

The Bilstein B8 5100 Rear Shock is engineered specifically for lifted suspension systems, ensuring the shock works with the geometry of a 4 inch lift rather than against it. Its 46mm monotube construction dissipates heat efficiently, helping maintain consistent damping during towing, hauling, and extended off road driving. Furthermore, Bilstein's velocity sensitive digressive valving reacts immediately to changing suspension movement, delivering firm control over larger impacts while remaining comfortable during everyday driving. The high pressure gas design minimizes oil foaming, allowing the shock to maintain reliable performance when the suspension is working hard. Split compression and rebound valving are tuned for this application, creating a balanced combination of stability, handling, and ride comfort. The smooth body, non adjustable design installs as a direct replacement without requiring additional adjustments after installation. Finished with a corrosion resistant zinc coating and an included black bellows boot, the 24-285698 is built to provide long lasting durability and dependable performance for lifted Ram 2500 owners.
