Description:
The FOX 2.5 Performance Elite HTO Rear Shock is the result of a dedicated engineering collaboration between Kryptonite and FOX. Working closely with FOX engineers, Kryptonite developed a proprietary rear shock application featuring custom Kryptonite-spec valving and FOX’s advanced Hydraulic Top-Out (HTO) technology. This specific HTO configuration is exclusive to the Kryptonite part number, delivering a purpose-built suspension solution engineered for exceptional ride quality and control across a range of GM heavy-duty trucks and SUVs.
FOX’s Hydraulic Top-Out technology provides position-sensitive rebound damping that controls shock shaft speed as the suspension approaches full extension. By directing shock oil through a secondary shim stack, HTO reduces harsh top-out events while maintaining a smooth, controlled ride both on and off the pavement. Combined with Kryptonite-specific valving, this technology helps improve suspension control and ride comfort, particularly on vehicles equipped with larger, heavier tires.
Rather than offering a standard off-the-shelf shock, Kryptonite worked directly with FOX to develop a unique combination of valving and HTO technology for these GM applications. The result is a premium rear shock designed to deliver refined ride quality, consistent control, and performance on and off the road.
