2005–2026 Ford F-250 / F-350 Super Duty Front Fox 2.5 Performance Series HTO Shock 0-1.5" Lift
Upgrade your suspension with the proven performance and reliability of Fox’s 2.5 Performance Series HTO shocks. Designed specifically for Ford Super Duty applications, this bolt-on shock delivers improved ride quality, control, and durability with position-sensitive technology, vehicle-specific valving, and a larger piston design for enhanced on- and off-road performance.
Key Features
- 2.5" impact extruded 6061-T6 aluminum shock body
- Type II clear-anodized body plating for corrosion resistance
- High-flow velocity-sensitive damping for consistent performance
- 5/8" hard chrome shock shaft for strength and durability
- Internal Floating Piston (IFP) design to separate oil and nitrogen
- Hydraulic Top Out (HTO) piston for position-sensitive rebound control
- Larger shock body for increased damping capacity
- Vehicle-specific valving for optimized ride quality
- Direct bolt-on installation
Performance Benefits
The integrated Hydraulic Top Out (HTO) technology provides usable position-sensitive rebound damping both on and off the pavement. By forcing shock oil through a secondary shim stack, HTO slows shock shaft speed near full extension—reducing harsh top-outs and improving overall ride comfort. This is especially beneficial for trucks running heavier tires or setups lifted beyond factory specifications.
