ICON K73063T 1.5-3.5" Stage 3 Suspension System With Tubular UCA

The Icon K73063T 1.5-3.5" Stage 3 Suspension System With Tubular UCA are designed to dramatically increase on and off-road ride quality of your 2019-2023 GM Silverado/Sierra 1500 2WD/4WD (See Application Notes). 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 3 system includes vehicle-specific tuned 2.5 Series coilover shocks featuring a remote 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 2.5 Aluminum Series piggyback reservoir 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 3 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.
