FOX 2.5 Performance Smooth Body HTO 0-1 inches Rear Lift IFP Shocks for 2011-2024 Chevrolet Silverado 3500HD

Part Number: 987-24-009

Summary: The FOX 2.5 Performance Series HTO shock is an aluminum body bolt-on solution designed to enhance both on and off-road performance for the Chevrolet Silverado 3500HD. Featuring an Internal Floating Piston (IFP) and position-sensitive technology, these shocks provide optimized damping by separating shock oil from high-pressure nitrogen. This system is engineered to increase damping capacity while maintaining ride comfort through specialized rebound control.

Features

• Internal Floating Piston (IFP): The 2.5-inch shock body utilizes an internal floating piston to separate shock oil from high-pressure nitrogen provides optimized damping to ensure consistent performance.
• Hydraulic Top Out (HTO): A secondary shim stack used to slow down shock shaft speed provides position-sensitive rebound damping control to ensure reduced harsh top-outs and increased comfort.
• 6061-T6 Aluminum Body: Impact extruded 2.5-inch aluminum with Type II clear-anodized plating provides efficient heat dissipation and corrosion resistance to ensure long-term durability.
• High-Flow Velocity-Sensitive Damping: Vehicle-specific valving and larger pistons provide rapid response to terrain changes to ensure improved handling on and off the pavement.

Why Choose This Product?

• Engineering Advantage: These shocks utilize Hydraulic Top Out (HTO) technology and an Internal Floating Piston (IFP) within a large 2.5-inch diameter aluminum body to manage heat and damping forces more effectively than standard shocks.
• Performance Benefit: Drivers experience reduced harshness during suspension extension and more consistent control when running heavier, aggressive tires or small rear lifts.

Frequently Asked Questions

What is the benefit of the Hydraulic Top Out (HTO) technology?
HTO reduces harsh top-outs by forcing shock oil through a secondary shim stack to slow the shaft speed, which increases comfort on and off the pavement.

What does the Internal Floating Piston (IFP) do?
The IFP separates the shock oil from the high-pressure nitrogen, which optimizes damping performance and prevents oil aeration.

Are these shocks compatible with lifted vehicles?
These shocks are specifically configured for vehicles with 0 to 1 inch of rear lift.
