Let Your Rear Suspension Keep Up With Your Build

If you're running aggressive tires or a small lift on your 2014-2025 RAM 2500 4WD, the FOX 2.5 Performance Smooth Body IFP HTO Rear Shock brings the control and comfort your truck's been missing. Whether you’re towing, hauling gear, or just dealing with uneven pavement, this rear shock helps your suspension respond the way it should. It’s built with FOX’s Hydraulic Top Out (HTO) technology, which smooths out those sharp rebounds that happen when your shocks hit full extension. This is especially useful when your truck is loaded down or bouncing through rough terrain. The result is a ride that feels more planted and far less jarring, both on and off the pavement. It’s made for drivers who use their truck hard but still want to enjoy a comfortable ride. If your current setup feels like it’s falling short, this shock makes a noticeable difference right out of the box.

Advanced Damping That Stays Cool Under Pressure

Built from race-proven engineering, the FOX 987-24-005 rear shock is a serious upgrade for anyone needing dependable performance over the long haul. It features a 2.5-inch impact-extruded 6061-T6 aluminum body that’s CNC machined for strength and coated with a clear anodized finish to prevent corrosion. Inside, an Internal Floating Piston (IFP) separates nitrogen gas from the oil, reducing cavitation and maintaining consistent damping under high-stress conditions. The HTO piston is tuned to provide additional rebound control when the shock reaches full extension, which protects your suspension and improves comfort. With 8.86 inches of travel, it gives your rear end the range it needs to stay stable on varying terrain. The 5/8-inch hard chrome shaft is built to handle years of abuse without showing signs of wear. From towing heavy loads to exploring rough trails, this shock delivers precise control without compromising durability.
