FOX 2.5 Performance Smooth Body HTO 0-1 inches Front Lift IFP Shocks for 2011-2019 Chevrolet Silverado 3500HD

Part Number: 987-24-030

Summary: The FOX 2.5 Performance Series HTO shocks are engineered to provide a significant upgrade for the 2011-2019 Chevrolet Silverado 3500HD. Featuring an Internal Floating Piston (IFP) and Hydraulic Top Out (HTO) technology, these shocks deliver position-sensitive rebound damping for enhanced control on and off the pavement. The larger 2.5-inch aluminum body ensures efficient heat dissipation and improved damping capacity compared to standard shock designs.

Features

• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping to ensure reduced harsh top-outs and increased comfort.
• Internal Floating Piston (IFP): The IFP design separates shock oil from high-pressure nitrogen to ensure optimized damping and consistent performance.
• Aluminum Shock Body: 2.5-inch impact extruded 6061-T6 aluminum with Type II clear-anodized plating provides efficient heat dissipation to ensure corrosion resistance and fade-free operation.
• High-Flow Damping: Velocity-sensitive damping technology provides vehicle-specific valving to ensure improved on and off-road handling.

Why Choose This Product?

• Engineering Advantage: The inclusion of Hydraulic Top Out (HTO) technology manages shock shaft speed through a secondary shim stack, specifically addressing the stresses of heavier tires and lifted applications.
• Performance Benefit: Drivers experience a reduction in harsh top-out sensations and more consistent damping, resulting in a more controlled and comfortable ride over varied terrain.

Frequently Asked Questions

What does the Hydraulic Top Out (HTO) technology do?
HTO technology uses a secondary shim stack to slow down shock shaft speed during rebound, which reduces harsh top-outs and increases overall ride comfort.

How does the Internal Floating Piston (IFP) improve performance?
The IFP separates the shock oil from the high-pressure nitrogen gas, which prevents aeration and allows the shock to provide consistent, optimized damping.

Is this shock body corrosion resistant?
Yes, the shock features a 6061-T6 aluminum body with Type II clear-anodized plating to prevent corrosion and help dissipate heat effectively.
