Fox Shocks 987-24-008 Performance Series HTO 2.5 Front Shock Lift 0-1" Chevrolet Silverado/GMC Sierra 2500/3500 20-25
FOX 2.5 Performance Series HTO
The FOX 2.5 Performance Series HTO is a bolt-on shock designed with position-sensitive technology, vehicle-specific valving, and larger pistons to improve on- and off-road performance.
Its Type II anodized aluminum body efficiently dissipates heat and resists corrosion. The 2.5-inch shock body features an internal floating piston (IFP) that separates shock oil from high-pressure nitrogen to optimize damping.
Hydraulic Top Out (HTO) technology provides usable position-sensitive rebound damping on and off pavement. HTO reduces harsh top-outs and increases comfort by forcing shock oil through a secondary shim stack to slow shock shaft speed.
- Bolt-on installation for straightforward replacement
- Position-sensitive rebound control for improved ride quality
- Enhanced heat dissipation and corrosion resistance
- IFP design for consistent damping performance
*Bolt-on design fits many applications; particularly beneficial when using heavier, aggressive tires or when the vehicle is lifted beyond OEM height. Verify vehicle-specific fitment before installation.
