FOX 2.5 Performance HTO 0-1.5 inches Rear Lift Shocks for 2017-2025 Ford F-250 Super Duty 4WD

Part Number: 987-24-001

Summary: The FOX 2.5 Performance Series HTO is a high-performance bolt-on shock designed specifically for the Ford F-250 Super Duty. Featuring position-sensitive technology and vehicle-specific valving, these shocks are engineered to enhance both on-road comfort and off-road capability. The 2.5-inch aluminum body provides superior heat dissipation and corrosion resistance, while the integrated Hydraulic Top Out (HTO) system manages rebound forces to prevent harsh top-outs during aggressive driving or when using heavier wheel and tire combinations.

Features

• Hydraulic Top Out (HTO): Secondary shim stack technology provides position-sensitive rebound damping to ensure increased comfort and reduced harshness during full extension.
• Internal Floating Piston (IFP): High-pressure nitrogen separation from the shock oil provides consistent damping to ensure optimal performance across various terrains.
• Aluminum Body: 2.5-inch 6061-T6 impact extruded aluminum provides efficient heat dissipation to ensure fade resistance and durability.
• Hard Chrome Shaft: 5/8-inch hard chrome plated heat-treated alloy steel provides a robust surface to ensure long-term seal integrity.

Why Choose This Product?

• Engineering Advantage: The utilization of position-sensitive technology and a Hydraulic Top Out (HTO) piston allows for specialized damping control that standard shocks cannot provide, specifically targeting the rebound stroke.
• Performance Benefit: Drivers experience a significant reduction in harsh “top-out” clunks and improved ride stability when equipped with larger, heavier tires or when operating at the limit of the suspension travel.

Frequently Asked Questions

What is Hydraulic Top Out (HTO) technology?
HTO is a position-sensitive rebound damping system that uses a secondary shim stack to slow down the shock shaft speed as it nears full extension, reducing harshness.

Do these shocks work with a lifted truck?
Yes, these shocks are specifically configured for Ford F-250 Super Duty 4WD models with 0 to 1.5 inches of rear lift.

What is the benefit of the Internal Floating Piston (IFP)?
The IFP separates the shock oil from the high-pressure nitrogen gas, which prevents oil aeration and ensures consistent, fade-free damping performance.
