Get The Most Out Of Your Lifted Cummins

If you’ve lifted your RAM and want it to ride as confidently as it looks, the FOX 985-24-022 2.0 Performance Series Reservoir Rear Shock is exactly what your suspension has been missing. Designed for 2003–2013 Dodge RAM 2500 and 3500 4WD models running a 2.5 to 3.5 inch rear lift, this shock delivers serious on-road comfort and dependable off-road control in one easy bolt-on upgrade. Whether you're towing, trail riding, or just heading out for a long highway cruise, it keeps your rear end planted and predictable through every condition. The external reservoir doesn't just look aggressive, it adds vital oil and nitrogen capacity, helping this shock perform without skipping a beat, even on rough terrain or in extreme heat. Drivers will immediately notice the improved ride quality, less rear-end bounce, and greater stability under load. It’s made for truck owners who use their RAM like a truck, and want premium performance without overcomplicating the build. This is one of those upgrades you feel from the first drive and never want to go without again.

Designed To Tame Heat Travel And Heavy Loads

The FOX 985-24-022 is built from the inside out to outperform your factory shocks in nearly every way. At its core is a 2.0 inch impact-extruded 6061-T6 aluminum body that not only resists corrosion but also dissipates heat more efficiently than standard steel. Its smooth body pairs with an external reservoir that increases oil and nitrogen capacity, reducing fade and keeping performance consistent during demanding conditions. This design separates the internal oil from high-pressure gas using FOX’s proven Internal Floating Piston, which virtually eliminates aeration and lag. A race-developed high-flow piston works in tandem with application-specific valving to give you the ideal balance of control and comfort, especially important on trucks with 2.5 to 3.5 inches of rear lift. FOX also integrates a redundant sealing pack system and quiet nitrile rubber bushings to help improve articulation, reduce noise, and protect against wear. Every detail in this shock is engineered to deliver a smoother, more confident ride for diesel-powered RAMs that don’t back down from a challenge.
