ICON 1-3″ Lift Kit Stage 4 (Aluminum) for 2014, 2015, 2016 GM Silverado/Sierra 1500 Truck

Part: K73004A


ICON Vehicle Dynamics 2014-2017 GM Silverado/Sierra 1500 suspension systems are designed to dramatically increase the on and off-road ride quality. ICON engineers’ primary focus is to increase wheel travel and damping ability, which translates into outstanding vehicle control and ride quality both on and off-road. With wheel travel and ride quality in mind, ICON engineers researched each component of the GM platform’s suspension and addressed any areas where performance could be extracted. The Stage 4 system provides a higher level of performance that will drastically improve overall on and off-road vehicle ride characteristics. ICON’s Vehicle-specific tuned 2.5” remote reservoir coilover shocks and ICON 2.5 Series piggyback rear shocks in this system provide exceptional cooling properties, with the coilovers utilizing ICON-engineered Eibach coil springs for superior vehicle “feel” throughout the range of travel. Remote reservoirs front and rear ensure optimum performance by increasing the duration of consistent damping, keeping the shocks at a cooler operating temperature during extended offroad use. These 2.5″ remote reservoir coilovers are also height adjustable from 0-3” allowing the use of larger, more aggressive wheel and tire combinations when desired. The ICON Vehicle Dynamics 2014-2017 GM Silverado/Sierra 1500 Stage 4 suspension system is an excellent choice for those drivers looking to enhance the capabilities of their pickup on the road as well as optimum performance in the dirt.
