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

Part Number: 987-24-035

Summary: The FOX 2.5 Performance Series HTO shocks are designed to provide high-performance damping for lifted Chevrolet Silverado 2500HD applications. These shocks feature position-sensitive damping technology and Hydraulic Top Out (HTO) to manage the increased mass of heavier tires and lift kits. By utilizing a 2.5-inch aluminum body and an Internal Floating Piston (IFP), these shocks ensure consistent control and heat dissipation during both on-road transit and off-road use.

Features

• Hydraulic Top Out (HTO): Secondary shim stack technology provides position-sensitive rebound damping control to ensure reduced harsh top-outs and increased comfort.
• Internal Floating Piston (IFP): High-pressure nitrogen separation from the shock oil provides optimized damping to ensure consistent performance by preventing aeration.
• Aluminum Shock Body: 2.5-inch impact extruded 6061-T6 aluminum provides efficient heat dissipation and corrosion resistance to ensure long-term durability.
• High-Flow Piston: Velocity-sensitive damping specs provide improved on and off-road performance to ensure a balanced ride quality.

Why Choose This Product?

• Engineering Advantage: The integration of Hydraulic Top Out (HTO) technology offers a position-sensitive rebound circuit that specifically addresses the mechanical stress of lifted suspension cycles.
• Performance Benefit: Drivers experience a significant reduction in harsh “clunking” or top-out sensations, especially when running heavier, aggressive tire setups.

Frequently Asked Questions

What is the benefit of the HTO technology?
Hydraulic Top Out (HTO) technology uses a secondary shim stack to slow down the shock shaft speed as it reaches full extension, reducing harsh top-outs and improving ride comfort.

Are these shocks compatible with my lift kit?
These shocks are specifically valved and sized for 2011-2019 Chevrolet Silverado 2500HD models equipped with 4 to 6 inches of rear lift.

How does the IFP improve performance?
The Internal Floating Piston (IFP) separates the nitrogen gas from the shock oil, which prevents oil foaming and ensures consistent damping performance under various conditions.
