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

Part Number: 987-24-030

Summary: The FOX 2.5 Performance Series HTO shocks are engineered to enhance both on and off-road performance for the GMC Sierra 2500HD. Featuring an Internal Floating Piston (IFP) within a 2.5-inch impact extruded aluminum body, these shocks provide optimized damping by separating shock oil from high-pressure nitrogen. This system is specifically designed to handle the increased demands of heavier tires and lifted applications, ensuring a controlled and comfortable ride through advanced position-sensitive technology.

Features

• Internal Floating Piston (IFP): The internal floating piston (IFP) design separates shock oil from the high-pressure nitrogen to provide optimized damping and consistent performance.
• Hydraulic Top Out (HTO): A Hydraulic Top Out (HTO) piston forces shock oil through a secondary shim stack to slow down shock shaft speed, providing position-sensitive rebound damping control and reducing harsh top-outs.
• Aluminum Shock Body: A 2.5-inch impact extruded 6061-T6 aluminum body with Type II clear-anodized plating provides efficient heat dissipation and prevents corrosion to ensure long-term durability.
• High-Flow Damping: High-flow velocity-sensitive damping combined with a 5/8-inch hard chrome shaft provides rapid response to terrain changes for improved vehicle control.

Why Choose This Product?

• Engineering Advantage: The combination of an Internal Floating Piston (IFP) and Hydraulic Top Out (HTO) technology allows for sophisticated position-sensitive rebound control that prevents the mechanical harshness typical of standard shocks.
• Performance Benefit: Drivers experience increased damping capacity and reduced top-out harshness, particularly when navigating rough terrain with aggressive tires or leveling kits.

Frequently Asked Questions

What is the benefit of the HTO technology?
Hydraulic Top Out (HTO) technology reduces harsh top-outs by using a secondary shim stack to slow the shock shaft speed during rebound, increasing comfort on and off the pavement.

How does the aluminum body improve performance?
The 2.5-inch impact extruded 6061-T6 aluminum body dissipates heat more efficiently than steel and features Type II anodizing to prevent corrosion.

Does this shock accommodate lifted vehicles?
Yes, these shocks are specifically configured for front lift heights ranging from 0 to 1 inch.
