FOX 2.5 Performance Smooth Body HTO 2-3.5 inches Rear Lift IFP Shocks for 2017-2025 Ford F-250 4WD

Part Number: 987-24-003

Summary: The FOX 2.5 Performance Series HTO shock is a bolt-on solution designed to improve on and off-road performance for the Ford F-250. Featuring an Internal Floating Piston (IFP), these shocks separate shock oil from high-pressure nitrogen to optimize damping consistency. The inclusion of Hydraulic Top Out (HTO) technology provides position-sensitive rebound control to mitigate harsh top-outs, especially in lifted applications or when running heavier tires.

Features

• Internal Floating Piston (IFP): The 2.5-inch shock body features an internal floating piston (IFP) to separate the shock oil from the high-pressure nitrogen provides optimized damping to ensure consistent performance.
• Hydraulic Top Out (HTO): A secondary shim stack forces shock oil to slow down shock shaft speed provides position-sensitive rebound damping control to ensure increased comfort and reduced harsh top-outs.
• Aluminum Shock Body: 2.5” Impact extruded 6061-T6 aluminum with Type II clear-anodized plating provides efficient heat dissipation and corrosion resistance to ensure long-term durability.
• High-Flow Damping: Velocity-sensitive damping technology provides vehicle-specific valving to ensure improved ride quality on and off the pavement.

Technical Specifications

Fitment

• 2017-2025 Ford F-250 4WD
• Note: Lift: 2-3.5 inches

What’s Included

• Includes 2 Shocks

Why Choose This Product?

• Engineering Advantage: The 2.5-inch aluminum body offers greater oil capacity and heat dissipation than smaller diameter shocks, while the IFP design prevents oil aeration.
• Performance Benefit: The Hydraulic Top Out (HTO) system specifically addresses the harshness often felt in lifted trucks, providing a smoother transition at the limit of the shock’s travel.

Frequently Asked Questions

What is the benefit of the Internal Floating Piston (IFP)?
The IFP separates the shock oil from the high-pressure nitrogen gas, which optimizes damping and prevents the oil from foaming.

How does Hydraulic Top Out (HTO) technology work?
HTO technology uses a secondary shim stack to slow down the shock shaft speed near full extension, reducing harsh top-out sensations.

What lift height are these shocks compatible with?
These shocks are designed for Ford F-250 4WD models with 2 to 3.5 inches of rear lift.
