• 4WD models only. Does not fit RWD Ram 2500.
• Does not fit Ram 2500 Power Wagon or Ram 3500.
• Valved for off-road and lifted applications - firmer than B6 4600 street-tuned shocks.
• Sold as a single unit. Install in pairs for balanced rear performance.

Features

• Bilstein B8 5100 series - designed as a direct-fit solution for Ram 2500 4WD trucks equipped with factory air ride suspension.
• 46mm monotube high-pressure gas design provides consistent, fade-free damping under towing, hauling, and off-road conditions.
• Velocity-sensitive digressive piston instantly adapts to changing road surfaces for improved control and stability.
• Application-specific valve tuning ensures optimal performance for the Ram 2500's suspension geometry and load capacity.

Product Description

The Bilstein 24-285667 is a rear B8 5100 shock absorber engineered specifically for 2014-2018 Ram 2500 4WD trucks equipped with factory air ride (air leveling) suspension. Unlike standard OE replacement shocks, the B8 5100 features off-road-oriented valve tuning and extended piston travel, making it the ideal upgrade for trucks that tow, haul heavy loads, or tackle demanding terrain. The 46mm monotube design eliminates the risk of oil foaming and delivers consistent damping force even under sustained load - conditions where conventional twin-tube shocks can fade.

This shock is a direct bolt-on replacement using factory mounting hardware, requiring no fabrication or modifications. It is specifically built for the Ram 2500's air suspension chassis, and will not interchange with non-air suspension models. For a full rear upgrade, install as a matched pair. Drivers should expect a firmer, more controlled ride compared to the factory shock, particularly when loaded or off-road.
