FOX 2.5 Performance Smooth Body HTO 4-6 inches Front Lift IFP Shocks for 2011-2019 Chevrolet Silverado 2500HD

Part Number: 987-24-032

Summary: The FOX 2.5 Performance Series HTO shocks are engineered to enhance the on and off-road performance of lifted Chevrolet Silverado 2500HD trucks. Featuring an Internal Floating Piston (IFP) and a larger 2.5-inch aluminum body, these shocks provide superior heat dissipation and consistent damping. This bolt-on solution is specifically designed for vehicles with 4-6 inches of front lift, utilizing position-sensitive technology to manage the increased demands of heavier tires and aggressive terrain.

Features

• Internal Floating Piston (IFP): The IFP design separates the shock oil from the high-pressure nitrogen gas to provide optimized damping and consistent performance.
• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping control to slow down shock shaft speed and reduce harsh top-outs.
• Aluminum Body: The 2.5-inch 6061-T6 impact-extruded aluminum body provides efficient heat dissipation and corrosion resistance via Type II clear-anodized plating.
• High-Flow Damping: Velocity-sensitive damping combined with a 5/8-inch hard chrome shaft ensures rapid response to terrain changes.

Frequently Asked Questions

What is the benefit of the Hydraulic Top Out (HTO) feature?
HTO technology uses a secondary shim stack to provide position-sensitive rebound control, reducing harsh top-outs and increasing comfort on and off the pavement.

Can these shocks be used with any lift kit?
These shocks are designed for 4-6 inches of front lift but are specifically noted not for use with lift kits that change the original equipment (OE) mounts.

How does the IFP design improve performance?
The Internal Floating Piston (IFP) separates the high-pressure nitrogen from the shock oil, which optimizes damping and prevents the oil from foaming during intense use.
