ICON 2019-2023 GM 1500, 1.5-3.5 Lift, Stage 1 Suspension System

ICON Vehicle Dynamics 2019-2023 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 1 system includes vehicle-specific tuned 2.5 Series coilover shocks featuring an internal reservoir for exceptional cooling properties and ICON-engineered Eibach coil springs for superior vehicle “feel” through the range of travel. These coilovers are also height adjustable from 1.5-3.5” allowing the use of larger, more aggressive wheel and tire combinations. ICON 2.0 Aluminum Series monotube rear shocks utilize a vehicle-specific valving that balances the performance of the truck from front to rear. The ICON Vehicle Dynamics 2019-2023 GM Silverado/Sierra 1500 Stage 1 suspension system is an excellent choice for those drivers looking to enhance the capabilities of their pickup on the road as well as in the dirt.
