ICON 2020-Up Chevrolet/GMC 2500/3500 Suspension System

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.

With three unique offerings to choose from, these systems are available with either tubular steel upper control arms or fully adjustable billet aluminum upper control arms, with both featuring alignment correction and ICON's patented heavy-duty Delta Joint. The entry level Stage 1 system includes your choice of upper control arms, 2.5 Aluminum Series Internal Reservoir front shocks, 2.0 Aluminum Series rear shocks and all necessary hardware to complete the installation. The Stage 2 system adds Remote Reservoirs to the 2.5 Aluminum Series front shocks and upgrades the rear to 2.5 Aluminum Series Piggyback Reservoir shocks. Finally, stepping up to the Stage 3 system adds ICON's Compression Damping Control Valve (CDCV) for 10 unique settings of tool-free adjustment to the shocks' firmness.
