FOX 2.5 Performance Smooth Body HTO 4-6 inches Front Lift IFP Shocks for 2017-2025 Ford F-350 Super Duty 4WD

Part Number: 987-24-020

Summary: The FOX 2.5 Performance Series HTO shocks are engineered for the 2017-2025 Ford F-350 Super Duty 4WD, specifically designed to handle front lift heights of 4 to 6 inches. These shocks utilize an Internal Floating Piston (IFP) to separate oil from high-pressure nitrogen, ensuring optimized damping and preventing aeration. By incorporating Hydraulic Top Out (HTO) technology, these shocks provide position-sensitive rebound control to mitigate harsh top-outs, especially in applications with heavier tires or increased ride heights.

Features

• Internal Floating Piston (IFP): The 2.5-inch internal floating piston (IFP) provides a physical barrier between the shock oil and high-pressure nitrogen to ensure consistent, fade-free damping performance.
• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping to ensure a reduction in harsh top-out events during high-extension maneuvers.
• 6061-T6 Aluminum Body: An impact-extruded 2.5-inch aluminum body provides efficient heat dissipation and corrosion resistance to ensure long-term durability in varied environments.
• Vehicle-Specific Valving: High-flow velocity-sensitive damping provides tailored suspension response to ensure improved on and off-road handling for the Super Duty platform.

Why Choose This Product?

• Engineering Advantage: The combination of a large 2.5-inch aluminum body and Hydraulic Top Out (HTO) technology allows for superior heat management and controlled rebound speed that standard shocks cannot match.
• Performance Benefit: Drivers experience increased comfort and reduced harshness when encountering full suspension extension, maintaining stability even with aggressive, heavy tire setups.

Frequently Asked Questions

What is the benefit of the HTO technology?
Hydraulic Top Out (HTO) technology reduces harsh top-outs by forcing shock oil through a secondary shim stack, slowing the shock shaft speed as it reaches full extension.

Is this shock compatible with stock height trucks?
No, these shocks are specifically valved and sized for Ford F-350 models with 4 to 6 inches of front lift.

What does the Internal Floating Piston (IFP) do?
The IFP separates the shock oil from the high-pressure nitrogen gas, which prevents oil aeration and allows for consistent damping across various terrains.
