Make Your Front End Feel Like New Again

If your RAM is running a 2.5 to 3.5 inch front lift and you’re still on stock shocks, you’re leaving serious performance on the table. The FOX 985-24-021 Performance Series Reservoir Front Shock is a purpose-built upgrade that transforms how your truck handles both on and off the road. From daily driving to rugged off-road use, this shock delivers smoother control and better ride feel without punishing your back. It’s a great pick for Cummins-powered RAMs from 2003–2013, as well as compatible gas models, and it bolts in without any drama. The added external reservoir doesn’t just look aggressive — it gives the shock more oil capacity, which means cooler temperatures and better long-term performance. You’ll feel the difference when tackling potholes, washboard trails, or towing heavy loads down the highway. This is the kind of upgrade that brings balance and confidence back to your lifted truck.

Designed To Handle What The Trail Throws At You

Built from a 2.0 inch impact-extruded 6061-T6 aluminum body, the FOX 985-24-021 is engineered for strength, heat resistance, and reliable long-term use. Its smooth clear-anodized finish helps protect the body from corrosion, while also improving thermal efficiency under tough driving conditions. The external reservoir adds oil and nitrogen capacity, which reduces heat build-up and shock fade during long runs. Inside, FOX uses a race-developed high-flow piston paired with application-specific valving that’s tailored to the ride dynamics of 2003–2013 RAM 2500 and 2003–2012 RAM 3500 4WD trucks. This setup helps maintain consistent performance whether you're carving through rough terrain or hauling a trailer on the open road. The redundant sealing system and nitrile rubber bushings keep things smooth and quiet, while also boosting suspension articulation for more flex and grip. Every element of this shock is purpose-built for demanding drivers who expect more from their suspension.
