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

Part Number: 987-24-009

Summary: The FOX 2.5 Performance Series HTO shocks are engineered to enhance both on and off-road performance for the GMC Sierra 3500HD. Featuring an Internal Floating Piston (IFP) and a 2.5-inch impact-extruded aluminum body, these shocks are designed to optimize damping while efficiently dissipating heat. The inclusion of Hydraulic Top Out (HTO) technology provides position-sensitive rebound control, specifically addressing the harshness associated with heavy tires and lifted applications.

Features

• Internal Floating Piston (IFP): A dedicated internal piston separates the shock oil from the high-pressure nitrogen to ensure optimized damping and consistent performance.
• Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping to ensure reduced harshness during top-out events and increased ride comfort.
• 6061-T6 Aluminum Body: A 2.5-inch impact-extruded aluminum body with Type II clear-anodized plating provides efficient heat dissipation to ensure corrosion resistance and sustained performance.
• Velocity-Sensitive Damping: High-flow valving provides specific tuning for the vehicle to ensure improved handling across various terrains.

Why Choose This Product?

• Engineering Advantage: The combination of an Internal Floating Piston (IFP) and Hydraulic Top Out (HTO) technology allows for sophisticated fluid management, preventing oil aeration and controlling rebound speeds through a secondary shim stack.
• Performance Benefit: Drivers experience a significant reduction in harsh top-out sensations and improved damping capacity, especially when the vehicle is equipped with heavier, aggressive tires.

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 and increases overall comfort.

How does the Internal Floating Piston (IFP) improve the ride?
The IFP separates the shock oil from the high-pressure nitrogen gas, which prevents oil aeration and allows the shock to provide consistent, optimized damping.

What is the construction of the shock body?
The shock features a 2.5-inch 6061-T6 impact-extruded aluminum body with Type II clear-anodized plating for heat dissipation and corrosion resistance.
