Part Number: 987-24-003

Summary: The FOX 2.5 Performance Series HTO shock is an aluminum-bodied, bolt-on solution designed to improve both on and off-road performance for the Ford F-350 Super Duty. Utilizing an Internal Floating Piston (IFP) and Hydraulic Top Out (HTO) technology, these shocks provide position-sensitive rebound damping to manage the weight of heavier tires and lift kits. The 2.5-inch impact-extruded body is designed to efficiently dissipate heat while providing increased damping capacity over standard shocks.

Features

• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping to ensure reduced harsh top-outs and increased comfort during high-extension events.
• Internal Floating Piston (IFP): High-pressure nitrogen gas is separated from the shock oil to provide optimized damping and consistent performance by preventing aeration.
• 6061-T6 Aluminum Body: The 2.5-inch impact-extruded body with Type II clear-anodized plating provides efficient heat dissipation and corrosion resistance to ensure long-term durability.
• High-Flow Piston: Velocity-sensitive damping technology provides vehicle-specific valving to ensure improved ride quality across varying terrain.

Why Choose This Product?

• Engineering Advantage: The combination of a larger 2.5-inch aluminum body and Hydraulic Top Out (HTO) technology allows for superior heat management and controlled rebound speed compared to standard shocks.
• Performance Benefit: Drivers experience a reduction in harsh “top-out” sensations and more consistent damping, especially when the vehicle is equipped with aggressive tires or increased lift heights.

Frequently Asked Questions

What is the benefit of the Hydraulic Top Out (HTO) technology?
HTO reduces harsh top-outs and increases comfort by forcing shock oil through a secondary shim stack to slow down the shock shaft speed during rebound.

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, fade-free damping performance.

Are these shocks compatible with lifted trucks?
Yes, these shocks are specifically configured for Ford F-350 Super Duty models with a 2-3.5 inch rear lift height.
