Summary: The FOX 2.5 Performance Series HTO shock is an impact-extruded aluminum body solution designed to enhance the ride quality of the Ford F-350 Super Duty. Featuring an Internal Floating Piston (IFP), this shock effectively separates shock oil from high-pressure nitrogen to ensure consistent damping performance across varying terrains. This specific model utilizes Hydraulic Top Out (HTO) technology to provide position-sensitive rebound control, addressing the harsh top-outs often experienced with lifted applications and heavier tire configurations.

Features

• Internal Floating Piston (IFP): An internal chamber separates shock oil from high-pressure nitrogen to provide optimized damping and prevent oil aeration.
• Hydraulic Top Out (HTO): A secondary shim stack forces shock oil to slow down shaft speed to provide position-sensitive rebound damping and ensure increased comfort by reducing harsh top-outs.
• Aluminum Shock Body: A 2.5-inch 6061-T6 impact-extruded aluminum body with Type II clear-anodized plating provides efficient heat dissipation to ensure corrosion resistance and sustained performance.
• High-Flow Velocity-Sensitive Damping: Vehicle-specific valving and larger pistons provide rapid response to impacts to ensure improved on and off-road control.
• Hard Chrome Shaft: A 5/8-inch hard chrome plated heat-treated alloy steel shaft provides durability to ensure long-term seal integrity.

Why Choose This Product?

• Engineering Advantage: The integration of an Internal Floating Piston (IFP) and Hydraulic Top Out (HTO) technology allows for a position-sensitive damping profile that manages rebound energy more effectively than standard shocks.
• Performance Benefit: Drivers experience a significant reduction in harsh “clunking” or top-out sensations, particularly when navigating rough terrain with heavier aftermarket wheels and tires.

Frequently Asked Questions

What is the benefit of the HTO technology in these shocks?
Hydraulic Top Out (HTO) technology uses a secondary shim stack to slow down the shock shaft speed during rebound, which reduces harsh top-outs and increases ride comfort.

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

How does the aluminum body help performance?
The 6061-T6 aluminum body dissipates heat more efficiently than traditional steel bodies and features Type II anodizing to prevent corrosion.
