Description
FOX Performance Series 2.5 shocks for the Chevrolet Silverado 1500 and GMC Sierra 1500 are a bolt-on solution with vehicle-specific valving and larger pistons to improve on and off-road performance. Level your vehicle without straining ball joints or linkages to maintain OEM reliability and vehicle behavior.
Monotube shocks utilize type II anodized aluminum bodies, efficiently dissipating heat and preventing corrosion. The 2.5-inch shock body features an internal floating piston (IFP) to separate the shock oil from the high-pressure nitrogen, optimizing damping.Β
Bolt-on Performance Series 2.5 shocks ride in comfort and increase damping capacity.
