ICON Vehicle Dynamics are world-renowned for their ultra high quality suspension systems and wheels. Every component is developed to help you get the best out of your GMC Sierra – whether you are driving on or off road. The ICON range of suspension systems features a variety of different levels or ‘stages’ for each vehicle model, to meet different needs or performance requirements.

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-UP 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. ICON’s Stage 2 system is comprised of V.S. 2.5 Aluminum Series remote reservoir front and rear shocks, and tubular Delta Joint upper control arms. The ICON vehicle specific tuned 2.5″ shocks are the key to attaining optimum ride quality and getting that desired comfort with the 3/4 & 1-ton working capability. Remote reservoirs ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use. Additionally, ICON billet upper control arms add strength, durability, additional caster and camber adjustment, and when paired with extended travel shocks increases wheel travel 2″ over the OEM configuration. 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. 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.
