Unlock Confident Control On Every Rugged Drive

If you're lifting your 2003–2013 RAM 2500 or 3500 and want a shock that doesn’t just survive tough terrain but thrives in it, the FOX 985-24-020 Performance Series 2.0 Rear Shock is what you want in your corner. This isn't just another aftermarket upgrade, it’s race-tested technology built for everyday off-roaders, overlanders, and diesel-driven haulers who want reliable performance without sacrificing ride quality. Whether you're weaving through rocky trails or hauling heavy loads down backroads, this shock delivers a comfortable, predictable ride every time. It’s been specifically tuned for 5.9L and 6.7L Cummins diesel setups, making sure your truck doesn’t just ride better but responds better under stress. The factory-tuned valving works hand-in-hand with the Internal Floating Piston to keep things smooth when the terrain gets sketchy. What sets it apart is the way it maintains composure even when you're putting the truck through its paces, no bouncing, no fade, just consistent control. If your rig's already running a 2.5 to 3.5 inch rear lift, this is the final piece to bring it all together and make the whole setup work the way it should.

Built With Precision To Outlast The Trail Ahead

Underneath the sleek anodized aluminum body of the FOX 985-24-020 is a carefully engineered shock built to take a beating while maintaining precision. The monotube design houses a race-developed high-flow piston paired with application-specific valving that works in harmony with RAM 2500 and 3500 4WD diesel trucks from 2003–2013. The Internal Floating Piston keeps the shock oil and nitrogen gas separated, which eliminates aeration and keeps your damping performance consistent, even during long or aggressive drives. The 2.0 inch diameter body is crafted from impact-resistant 6061-T6 aluminum, helping to dissipate heat and resist corrosion far better than traditional steel-bodied shocks. Every component down to the nitrile rubber bushings is built for long-term durability and smooth operation, offering increased suspension articulation when it matters most. This shock is designed to handle rough environments, from deep ruts to loose gravel, and is equally capable whether you're loaded up for work or playing off the clock. Backed by FOX’s reputation and proven suspension technology, it's a reliable upgrade for drivers who expect more out of their trucks.
