FOX 2.5 Performance Smooth Body HTO 0-1 inches Front Lift IFP Shocks for 2011-2019 Chevrolet Silverado 2500HD

Part Number: 987-24-030

Summary: The FOX 2.5 Performance Series HTO shock is a bolt-on solution engineered to enhance both on and off-road performance for the Chevrolet Silverado 2500HD. Featuring position-sensitive damping technology and larger pistons, these shocks are designed to increase damping capacity and improve ride quality. The integration of Hydraulic Top Out (HTO) technology specifically addresses harsh top-outs, providing controlled rebound damping through a secondary shim stack to ensure comfort even with heavier, aggressive tire setups.

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 shaft speed events.
• Internal Floating Piston (IFP): The internal floating piston (IFP) separates shock oil from high-pressure nitrogen gas to ensure optimized damping and prevent oil aeration.
• Aluminum Body: A 2.5-inch impact extruded 6061-T6 aluminum shock body provides efficient heat dissipation and corrosion resistance through Type II clear-anodized plating to ensure consistent performance.
• High-Flow Damping: Velocity-sensitive damping technology provides rapid response to terrain changes to ensure a controlled and stable ride.

Why Choose This Product?

• Engineering Advantage: The 2.5-inch aluminum body offers superior heat management compared to smaller diameter shocks, while the position-sensitive HTO technology manages energy at the limits of suspension travel.
• Performance Benefit: Drivers experience a significant reduction in harsh “clunking” or top-out sensations, resulting in a smoother ride when navigating obstacles or running aggressive wheel and tire combinations.

Frequently Asked Questions

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

Does this shock help with heavier tires?
Yes, the HTO technology is particularly beneficial for applications with heavier, aggressive tires that can cause increased suspension stress.

What is the construction of the shock body?
The shock features a 2.5-inch impact extruded 6061-T6 aluminum body with Type II clear-anodized plating for heat dissipation and corrosion resistance.
