Product details
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 Chevrolet Silverado 2500 HD/3500 HD and GMC Sierra 2500 HD/3500 HD 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 3 3.0 system is comprised of CDEV equipped V.S. 3.0 Series remote reservoir front and rear shocks, billet aluminum Delta Joint Pro HD upper control arms, rear leaf spring packs, and torsion keys that allow for 2-3.5” of front lift height adjustment. The ICON vehicle specific tuned 3.0 Series shocks with CDEV are the key to attaining optimum ride quality and getting that desired comfort with the 3/4 & 1-ton working capability with their larger diameter, piston area, internal bump zones, and oil volume working to control rough terrain better than smaller diameter shocks. Remote reservoirs also greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. Focus on driving and let ICON Intelligent Control (IIC) read the terrain and make near-instant adjustments via the Compression Damping Electronic Valve (CDEV) at each individual shock. Control the system wirelessly through the IIC app on your phone and once configured the system functions without driver input.
- Adjustable for 2-3.5” of front lift height over stock
- Vehicle specific tuned 3.0 Series remote reservoir front and rear shocks for the ultimate in shock damping and control
- ICON's CDE Valve technology allows for in vehicle adjustment of compression damping settings and active adjustment via the ICON Intelligent Control (IIC)
- ICON Intelligent Control (IIC) uses onboard sensors to monitor G-forces and movement of vehicle chassis along with user defined settings to actively make near instantaneous compression damping changes
- Improved ride quality and suspension performance over stock
- Billet aluminum Delta Joint Pro HD UCAs allow for additional caster/camber adjustment
- Forged steel torsion keys
- Front wheel travel increase of approximately 3" over stock
- Rear leaf springs lower spring rate and increase distance to overload engagement compared to stock to greatly improve rear ride quality
- Leaf springs maintain stock rear ride height for a level stance with the front
- 6061 Aircraft grade aluminum CNC machined components
- Corrosion resistant hard anodized aluminum shock bodies
- 100% Bolt-on system - no drilling, cutting, or welding necessary for install
