Soft and supple for a smooth highway ride, the factory shocks of the Chevy Silverado 1500 or its GMC twin simply can’t hang in the dirt. Like Danny Devito doing bench presses, the OEM shocks quickly get overwhelmed. The result is a rough ride, getting tossed around the cab, and slow going in anything slightly rough. Fox's Performance Elite Series shocks eliminate this poor performance in the dirt. With 2.5-inch diameter impact extruded aluminum shock bodies, Fox's shocks hold more fluid and have larger valving pistons. The result is an increase in damping force and fade-free performance with shock fluid temperatures remaining in check. Every Fox shock is valved specifically for its application so that compression and rebound are spot on. Fox's innovative DSC adjusters allow for further fine tuning of both low- and high-speed compression. Translation? Your Silverado or Sierra will work way better in the dirt while still having a comfortable highway ride.
