ICON Vehicle Dynamics K73104 - 21-23 GM SUV 2.5-3.25" STAGE 4 SUSPENSION SYSTEM BILLET

ICON 21-26 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 2021-2026 Chevrolet Tahoe/Suburban and 2021-2026 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. Billet aluminum Delta Joint upper control arms not only add strength and durability but help retain factory alignment specs and offer on-vehicle caster/camber adjustment. The system also includes fabricated rear toe links for proper rear-end alignment at the new, taller ride heights, ensuring optimal handling. Additionally, ICON offers the necessary components to make this system compatible with all submodels and configurations that these vehicles are offered from the manufacturer, including those equipped with Magnetic Ride control and/or Adaptive Air Ride suspension. Features like these make the ICON Vehicle Dynamics 2021-2026 Chevrolet Tahoe/Suburban and 2021-2026 GMC Yukon/Yukon XL Stage 4 suspension system an excellent choice for those drivers looking to enhance the capabilities of their SUV on the road as well as in the dirt. This system features billet aluminum upper control arms with ICON's patented Delta Joint. The Delta Joint is a heavy-duty high angle ball joint that combines the durability of a ball joint with the performance characteristics of a traditional uniball. While the industry standard uniball does a great job of allowing the control arms of a vehicle to articulate with little bind, they do have an inherent weakness that leaves more to be desired when used in a daily driven application - exposure to the elements. The Delta Joint features a zinc plated housing providing the first layer of corrosion resistance, while a tough grease seal keeps potentially harmful elements out of the inner workings of the joint. Metal on metal construction and a greaseable design increase the longevity of the Delta Joint while at the same time allowing for noise-free operation. What makes the Delta Joint unique is that it brings the best of both worlds to ICON upper control arms with features that make it more robust than a uniball, and at the same time capable of greater angularity than a typical ball joint.
