ICON Vehicle Dynamics suspension lift kit.
Tougher, stronger and more capable - That's the motto that General Motors used when debuting the all-new fleet of heavy-duty trucks in 2020. ICON Vehicle Dynamics stayed true to GM engineers' thought process with the development of our suspension systems for the 2020-2026 GM HD 2500/3500 trucks. Using ICON's holistic engineering philosophy, our R&D team went above and beyond to develop several stages of complete suspension systems that provide varying levels of adjustability, capability, and overall vehicle performance. The ICON vehicle specific tuned 2.5" front shocks are the key to attaining optimum ride quality and getting that desired comfort with the 3/4 & 1-ton working capability. While driving the construction site or trails to your favorite dirt bike location, ICON wants you to get there in comfort just like your drive to work. This system features 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. 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.
A suspension lift raises ride height to clear larger tires; component kits vary in what they include, so check the parts list.
