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, providing position-sensitive rebound damping control. By utilizing a secondary shim stack to slow down shock shaft speed, HTO significantly reduces harsh top-outs and increases overall ride comfort. This is particularly beneficial for heavy-duty trucks equipped with heavier, more aggressive tires or those lifted above OEM specifications.
