The FOX 2.5 Performance Series HTO shock is a bolt-on upgrade equipped with position-sensitive technology, vehicle-specific valving, and larger pistons to enhance both on-road and off-road performance. It features a Type II anodized aluminum body that effectively dissipates heat and resists corrosion. The 2.5-inch shock body incorporates an internal floating piston (IFP) to separate shock oil from high-pressure nitrogen, optimizing damping performance. The Hydraulic Top Out (HTO) technology provides position-sensitive rebound damping control, improving comfort and reducing harsh top-outs. This feature is particularly beneficial for vehicles with heavier, aggressive tires and aftermarket lift kits. Install the FOX 2.5 Performance Series HTO shocks to experience greater damping capacity and a smoother ride with enhanced rebound control.

Features:

• 2.5” impact-extruded 6061-T6 aluminum shock body
• Type II clear-anodized body plating for corrosion resistance
• High-flow velocity-sensitive damping
• 5/8” hard chrome shaft for durability
• Internal floating piston (IFP) for consistent performance
• Hydraulic Top Out (HTO) piston for smoother rebound

Notes:

• 4-6″ shocks are only for use with lift kits that alter OE mounts.
• 6.5″ shocks are compatible with raised torsion systems that require lower eyelet mounting. These will not fit OE mounts.
