FOX 2.5 Performance Smooth Body HTO 0-1 inches Rear Lift IFP Shocks for 2011-2024 Chevrolet Silverado 2500HD

Part Number: 2×987-24-009

Summary: The FOX 2.5 Performance Series HTO is a specialized bolt-on shock designed to enhance the handling and ride quality of the Chevrolet Silverado 2500HD. Featuring an Internal Floating Piston (IFP) and a larger 2.5-inch aluminum body, this shock addresses the need for improved heat dissipation and consistent damping on and off-road. The integration of Hydraulic Top Out (HTO) technology provides position-sensitive rebound control, specifically engineered to mitigate harsh top-outs often experienced with heavier tires or lifted applications.

Features

• Internal Floating Piston (IFP): The internal floating piston (IFP) separates the shock oil from the high-pressure nitrogen to ensure optimized damping and consistent performance.
• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping control to ensure reduced harsh top-outs and increased comfort.
• Impact Extruded Aluminum Body: 2.5” 6061-T6 aluminum construction provides efficient heat dissipation and Type II clear-anodized corrosion resistance to ensure long-term durability.
• High-Flow Valving: Velocity-sensitive damping provides vehicle-specific tuning to ensure improved on and off-road performance.

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 prevents oil aeration and allows the shock to provide consistent, fade-free damping performance.

How does Hydraulic Top Out (HTO) technology work?
HTO technology forces shock oil through a secondary shim stack to slow down the shock shaft speed at the end of its travel, reducing harsh top-outs and increasing ride comfort.

What lift height are these shocks compatible with?
These shocks are specifically valved and sized for the rear of a Chevrolet Silverado 2500HD with 0 to 1 inch of lift.
