ICON Vehicle Dynamics 2019-2023 GM Silverado/Sierra 1500 suspension systems are designed to dramatically increase 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 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” of lift over stock 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.

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.
