ICON 71656C GM 1500 0-3.5″ Lift Front 2.5 VS Ext Travel RR/CDCV Coilover Kit

The ICON Vehicle Dynamics V.S. 2.5 Series remote reservoir coilover shocks are an incredible upgrade for the front end of the 2019-2023 GM Silverado/Sierra 1500. ICON’s Vehicle-specific valving provides a sport tuned feel on and off-road while offering 1.5-3.5″ of lift height adjustability for use of larger, more aggressive wheel and tire combinations. ICON’s larger 2.5″ shock body and increased piston area over stock components provides improved damping ability and outstanding ride characteristics across varying types of terrain. Remote reservoirs ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use. The ICON CDC Valve upgrade is included for those desiring an easy way to tune the ride externally with 10 adjustment settings from soft to hard. When paired with ICON 2.0 Aluminum Series or 2.5 Series rear shocks, vehicle control will be balanced front to rear resulting in the best overall driving experience for your GM truck.
