The FOX 2.5 Performance Series HTO Shocks Front Pair are high-performance, bolt-on shocks designed for 4-6 inch lift applications on the 2011-2019 GMC Sierra 2500 HD. Featuring vehicle-specific valving, larger pistons, and position-sensitive technology, these shocks enhance both on-road and off-road handling. The 2.5-inch shock body incorporates an internal floating piston (IFP) that separates shock oil from high-pressure nitrogen, optimizing damping and ride quality. Constructed with a type II anodized aluminum body, they efficiently dissipate heat and resist corrosion, ensuring durability and consistent performance under demanding conditions. The package includes all necessary hardware such as washers, bushings, and nuts, and is protected by Fox’s limited one-year warranty against defects and premature failure.

Designed specifically for 2011-2019 GMC Sierra 2500 HD models with a 4-6 inch lift, these shocks serve as direct replacements and performance upgrades for front suspension components. They are ideal for off-road enthusiasts, heavy-duty towing, or daily drivers seeking improved stability and ride comfort. The kit contains a pair of shocks, with options to select the appropriate length based on your lift height. Installation is straightforward, making these shocks suitable for those looking to enhance their vehicle’s off-road capability or overall handling. Compatibility is confirmed for vehicles with the specified lift range, ensuring a precise fit and reliable performance.
