FOX 2.5 Performance Smooth Body HTO 0-1.5 inches Front Lift IFP Shocks for 2014-2025 Ram 2500 4WD

Part Number: 987-24-004

Summary: The FOX 2.5 Performance Series HTO is a bolt-on shock absorber designed to enhance the handling of the Ram 2500 4WD. Featuring an Internal Floating Piston (IFP) and a 2.5-inch aluminum body, this shock is engineered to dissipate heat efficiently while separating oil from high-pressure nitrogen to optimize damping. The integration of Hydraulic Top Out (HTO) technology provides position-sensitive rebound control, specifically addressing the harshness often associated with heavier tires and lifted applications.

Features

• Internal Floating Piston (IFP): The internal floating piston (IFP) separates the shock oil from the high-pressure nitrogen to provide consistent damping and optimized performance.
• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping control to ensure reduced harshness during top-out events.
• Aluminum Shock Body: The 2.5-inch 6061-T6 impact extruded aluminum body provides efficient heat dissipation and corrosion resistance to ensure long-term durability.
• Velocity-Sensitive Damping: High-flow valving provides rapid response to terrain changes to ensure improved on and off-road control.
• Hard Chrome Shaft: A 5/8-inch hard chrome plated heat-treated alloy steel shaft provides increased strength to ensure reliable operation under load.

Technical Specifications

Fitment

• 2014-2025 Ram 2500 4WD
• Note: Configured for front lift heights of 0-1.5 inches.

What’s Included

• Includes 2 Shocks

Why Choose This Product?

• Engineering Advantage: The 2.5-inch large-bore aluminum body increases oil capacity and cooling surface area compared to standard shocks, while the HTO piston manages rebound energy through a dedicated secondary shim stack.
• Performance Benefit: Drivers experience reduced suspension clunking and improved comfort, especially when running aggressive tires or leveling kits that typically stress factory rebound limits.

Frequently Asked Questions

What is the benefit of the HTO technology?
Hydraulic Top Out (HTO) technology provides position-sensitive rebound damping by forcing oil through a secondary shim stack, which slows down the shock shaft speed to reduce harsh top-outs.

Is this shock compatible with lifted trucks?
Yes, these shocks are specifically designed for 2014-2025 Ram 2500 4WD models with 0 to 1.5 inches of front lift.

How does the IFP design improve performance?
The Internal Floating Piston (IFP) separates the shock oil from the high-pressure nitrogen gas, which prevents oil aeration and allows for consistent, fade-free damping.
