ICON 21-23 GM SUV suspension systems are designed to increase wheel travel and damping ability, which translates into outstanding vehicle control and ride quality both on and off-road.
ICON Vehicle Dynamics 2021-2023 Chevrolet Tahoe/Suburban and 2021-2023 GMC Yukon/Yukon XL suspension systems are designed with maximum performance and the serious driver in mind. 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 vehicle platform’s suspension and addressed any areas where performance could be extracted. This Stage 4 system includes vehicle-specific tuned front and rear 2.5 Series coilover shocks featuring remote reservoirs for exceptional cooling properties and ICON-engineered coil springs for superior vehicle “feel” through the range of travel. These coilovers are also height adjustable from 2.5-3.25” of front lift and 3-4” of rear lift over stock for an aggressive stance and allowing the use of larger, more aggressive wheel and tire combinations. ICON 2.5 Series coilover shocks feature a vehicle-specific valving that balances the performance of the truck from front to rear. ICON's exclusive Compression Damping Control Valves are included for precisely dialing in your suspension performance. CDCV controls fluid flow under compression, allowing you to achieve the perfect tune whether driving on the street, slow-crawling through the rocks or mobbing across the desert at full throttle.
