Description:
The FOX 2.5 Performance Elite HTO Shock for 2001–2010 Chevrolet Silverado and GMC Sierra 2500HD/3500HD trucks is the result of a dedicated engineering collaboration between Kryptonite and FOX. Working closely with FOX engineers, Kryptonite developed a proprietary 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 on the GM HD platform.
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 maximize usable suspension travel and improve ride comfort, particularly on trucks equipped with larger, heavier tires or lifted beyond factory ride height.
Rather than offering a standard off-the-shelf shock, Kryptonite worked directly with FOX to develop a unique combination of valving and HTO technology specifically for the 2001–2010 GM HD platform. The result is a premium shock designed to deliver the ride quality, control, and performance these trucks deserve.
