Construction & Design

The FOX 2.0 Performance Series rear shock features a smooth body design crafted from high-strength materials to resist corrosion and wear. The internal floating piston separates the oil and nitrogen gas chambers, preventing aeration and maintaining consistent damping throughout the shock’s stroke. This design enhances durability and performance under demanding conditions, such as towing, hauling, and off-road driving.

FOX engineers have optimized the valving to provide a balance between firm control and ride comfort, making these shocks suitable for daily driving as well as aggressive off-road use. The robust construction ensures long service life and reliable operation even in extreme environments.

Installation & Fitment

These rear shocks are designed as direct replacements for the rear suspension on Ram 2500 trucks with 4 to 6-inch lift kits. Installation is straightforward and typically requires no special modifications or additional components. Vehicle owners can expect a bolt-on upgrade that improves suspension performance while maintaining factory mounting points and alignment.

Proper fitment is confirmed for 2014–2025 Ram 2500 models equipped with 6.7L Cummins diesel engines, 6.4L HEMI 392 engines, and 2014–2018 models with the 5.7L HEMI engine. Always verify compatibility with your specific vehicle configuration before installation.
