FOX 2.5 Performance Smooth Body HTO 1.5-2.5 inches Rear Lift IFP Shocks for 2011-2024 Chevrolet Silverado 2500HD

Part Number: 987-24-011

Summary: The FOX 2.5 Performance Series HTO is a bolt-on smooth body shock designed to enhance both on and off-road performance for the Chevrolet Silverado 2500HD. Featuring position-sensitive damping technology and a larger 2.5-inch piston, these shocks are engineered to manage the increased demands of vehicles with 1.5-2.5 inches of rear lift. The integration of Hydraulic Top Out (HTO) technology specifically addresses harsh rebounds, ensuring sustained comfort and control during high-extension events.

Features

• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping control to ensure reduced harsh top-outs and increased comfort.
• Internal Floating Piston (IFP): The internal floating piston (IFP) separates shock oil from high-pressure nitrogen gas to ensure optimized damping and consistent performance.
• Aluminum Shock Body: A 2.5-inch 6061-T6 impact extruded aluminum body provides efficient heat dissipation and prevents corrosion to ensure long-term durability.
• High-Flow Damping: Velocity-sensitive damping with a 5/8-inch hard chrome shaft provides rapid response to terrain changes to ensure improved vehicle stability.

Why Choose This Product?

• Engineering Advantage: The 2.5-inch aluminum body offers superior heat management compared to smaller diameter shocks, while the HTO piston provides a mechanical solution to slow shaft speeds during full extension.
• Performance Benefit: Drivers experience a significant reduction in “topping out” harshness, which is particularly beneficial when running heavier, aggressive tires or lifted suspension configurations.

Frequently Asked Questions

What is the benefit of Hydraulic Top Out (HTO) technology?
HTO technology reduces harsh top-outs by forcing shock oil through a secondary shim stack, which slows down the shock shaft speed during rebound extension.

Are these shocks compatible with stock height trucks?
These specific shocks are configured for vehicles with 1.5 to 2.5 inches of rear lift.

How does the Internal Floating Piston (IFP) improve the ride?
The Internal Floating Piston (IFP) separates the nitrogen charge from the shock oil, which prevents aeration and allows for more consistent damping performance on and off-road.
