Fox direct replacement shocks deliver race-winning performance in a simple, bolt-on package. These Performance Series 2.5 shocks feature FOX’s innovative Hydraulic Top Out (HTO) technology, which provides position-sensitive rebound damping. By forcing shock oil through a secondary shim stack to slow down shaft speed, HTO significantly reduces harsh top-outs. This is especially beneficial for heavy-duty trucks with aggressive tire setups or leveled suspension, ensuring a smooth, controlled ride on and off the pavement.
