FOX 2.5 Performance Smooth Body HTO 4-6 inches Rear Lift IFP Shocks for 2017-2025 Ford F-350 4WD
Part Number: 987-24-021
Summary: The FOX 2.5 Performance Series HTO shock is a bolt-on solution designed specifically for the rear of the Ford F-350 4WD. This series utilizes an Internal Floating Piston (IFP) to separate shock oil from high-pressure nitrogen, ensuring consistent damping across various terrains. By integrating position-sensitive technology and a larger 2.5-inch aluminum body, these shocks resolve the harshness often associated with lifted applications and heavier tire setups.
Features
- Internal Floating Piston (IFP): The IFP design separates shock oil from the high-pressure nitrogen gas chamber to provide optimized damping and prevent oil aeration.
- Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping control to ensure reduced harshness during full suspension extension.
- Aluminum Body: The 2.5-inch impact extruded 6061-T6 aluminum body provides efficient heat dissipation and corrosion resistance to ensure sustained performance.
- Hard Chrome Shaft: A 5/8-inch hard chrome plated heat-treated alloy steel shaft provides increased durability to ensure long-term seal integrity.

Why Choose This Product?
- Engineering Advantage: The combination of a large 2.5-inch diameter body and Hydraulic Top Out (HTO) technology allows for greater oil capacity and specific rebound control that standard shocks cannot match.
- Performance Benefit: Drivers experience a significant reduction in harsh top-outs and improved ride comfort, especially when running aggressive tires or higher lift heights.
Frequently Asked Questions
What is the benefit of the HTO technology?
Hydraulic Top Out (HTO) technology provides position-sensitive rebound damping, which slows down the shock shaft speed at the end of its travel to reduce harshness.
Are these shocks compatible with stock height trucks?
No, these shocks are specifically designed and valved for Ford F-350 4WD models with 4 to 6 inches of rear lift.
How does the IFP improve performance?
The Internal Floating Piston (IFP) separates the nitrogen gas from the shock oil, which prevents oil foaming and ensures consistent damping performance during off-road use.
