FOX 2.5 Performance Smooth Body HTO 4-6 inches Front Lift IFP Shocks for 2020-2024 GMC Sierra 2500HD
Part Number: 987-24-033
Summary: The FOX 2.5 Performance Series HTO shocks are engineered to provide advanced position-sensitive damping for the GMC Sierra 2500HD. By utilizing a 2.5-inch aluminum body and an Internal Floating Piston (IFP), these shocks address the need for increased heat dissipation and consistent damping control on vehicles equipped with 4-6 inch lifts. The integration of Hydraulic Top Out (HTO) technology ensures a smoother ride by managing rebound forces, specifically addressing the harshness often associated with larger, heavier wheel and tire combinations.
Features
- Hydraulic Top Out (HTO): A secondary shim stack provides position-sensitive rebound damping to ensure reduced harshness during full suspension extension.
- Internal Floating Piston (IFP): The internal mono-tube design separates shock oil from high-pressure nitrogen to ensure optimal damping and fade-free performance.
- 6061-T6 Aluminum Body: A 2.5-inch impact extruded aluminum body provides high heat dissipation to ensure consistent performance under load.
- High-Flow Velocity-Sensitive Damping: Vehicle-specific valving and larger pistons provide improved control to ensure superior on and off-road handling.

Frequently Asked Questions
What is Hydraulic Top Out (HTO) technology?
HTO is a position-sensitive rebound damping system that forces oil through a secondary shim stack to slow the shock shaft near full extension, reducing harsh top-outs.
Does this shock require a specific lift height?
Yes, these shocks are configured specifically for vehicles with a 4-6 inch front lift height.
Are these shocks compatible with all lift kits?
These shocks are not for use with lift kits that change the original equipment (OE) shock mounts.
