Key Features

Built with FOX’s race-proven technology, the 2.5 Performance Series IFP HTO Shock offers a range of features that optimize suspension performance for heavy-duty trucks like the Ram 3500:

• Internal Floating Piston (IFP) design for consistent damping and reduced fade
• High-Temperature Oil (HTO) formulation to maintain performance in extreme conditions
• Race-proven damping control for a smooth on-road ride and confident off-road handling
• Precision valving tuned specifically for Ram 3500 rear suspension dynamics
• Durable construction to withstand heavy loads and harsh environments
• Improved wheel control for enhanced traction and stability
• Corrosion-resistant finish for long-lasting durability
• Designed to fit factory mounting points for straightforward installation

Construction & Design

FOX Performance Series shocks are crafted with high-quality materials and advanced engineering to ensure durability and reliability. The 2.5-inch shock body is constructed from robust steel, providing strength to handle the weight and demands of heavy-duty trucks. The internal floating piston separates the oil and nitrogen gas, preventing aeration and maintaining consistent damping performance even under extended use.

The High-Temperature Oil (HTO) used inside the shock is specially formulated to resist breakdown and maintain viscosity in extreme heat, ensuring the shock performs reliably during intense off-road excursions or heavy towing. The shock’s valving is precisely calibrated to balance comfort and control, delivering a refined ride without sacrificing rugged capability.

Installation & Fitment

This FOX 2.5 Performance Series IFP HTO Shock is designed as a direct replacement for the rear shocks on 2014–2018 Ram 3500 5.7L Hemi, 2014–2025 Ram 3500 6.4L 392, and 2014–2025 Ram 3500 6.7L Diesel models. Installation requires no modifications, as the shock mounts to factory mounting points using existing hardware. Professional installation is recommended to ensure proper torque specifications and alignment for optimal performance.
