FOX 2.5 Performance Smooth Body HTO 0-1 inches Front Lift IFP Shocks for 2020-2024 GMC Sierra 3500HD
Part Number: 987-24-008
Summary: The FOX 2.5 Performance Series HTO shock is a bolt-on solution designed specifically for the GMC Sierra 3500HD to enhance both on and off-road performance. Utilizing position-sensitive technology and a larger 2.5-inch diameter body, these shocks provide increased damping capacity and superior heat dissipation compared to standard components. The inclusion of Hydraulic Top Out (HTO) technology ensures controlled rebound damping, specifically addressing the harshness often associated with heavier, aggressive tires or lifted applications.
Features
- Internal Floating Piston (IFP): The internal floating piston (IFP) separates shock oil from the high-pressure nitrogen to provide optimized damping and consistent performance.
- Hydraulic Top Out (HTO): A Hydraulic Top Out (HTO) piston forces shock oil through a secondary shim stack to slow down shock shaft speed and reduce harsh top-outs.
- 6061-T6 Aluminum Body: An impact extruded 6061-T6 aluminum body with Type II clear-anodized plating provides efficient heat dissipation and prevents corrosion to ensure long-term durability.
- Position-Sensitive Damping: Vehicle-specific valving and position-sensitive technology provide rebound control to ensure ride comfort on and off the pavement.

Why Choose This Product?
- Engineering Advantage: The 2.5-inch aluminum body offers a larger piston and increased fluid capacity compared to standard shocks, while the HTO technology provides secondary rebound damping specifically for the end of the shock stroke.
- Performance Benefit: Drivers experience a reduction in harsh top-out sensations and improved damping consistency, making this an ideal upgrade for vehicles equipped with heavy wheel and tire packages.
Frequently Asked Questions
What is the benefit of the Hydraulic Top Out (HTO) technology?
HTO technology provides position-sensitive rebound damping by forcing oil through a secondary shim stack, which slows the shaft speed to reduce harsh top-outs and increase comfort.
Are these shocks compatible with lifted vehicles?
Yes, these shocks are specifically configured for front lift heights of 0-1 inch on the 2020-2024 GMC Sierra 3500HD.
How does the Internal Floating Piston (IFP) improve performance?
The IFP separates the shock oil from the high-pressure nitrogen gas, which prevents oil aeration and allows for consistent damping performance across various terrains.
