Level up your 2020-2026 GM HD with this complete ICON suspension system. 2-3.5" of lift gets you the clearance for bigger tires without killing your ride quality. Everything in this kit is tuned to work together — springs, shocks, and hardware designed as a complete package.

Features

• Adjustable for 2-3.5" of front lift height over stock
• Vehicle specific tuned 2.5 Aluminum Series remote reservoir front and piggyback reservoir rear shocks for superior 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

Wheel & Tire Recommendations

• ICON Alloys - 18x9" w/ 5.5" Backspace / 12mm Offset
• ICON Alloys - 20x9" w/ 5.5" Backspace / 12mm Offset
• Tires: 35" x 12.50" (Larger tires may fit but fender trimming and modifications will be required.)

Important Notes

• Will not fit Cab & Chassis models
• Chevrolet Silverado 2500 ZR2 and GMC Sierra 2500 AT4X will have front lift height range of .5-2" over stock
• Helper air bags are recommended for hauling/towing heavy loads
• These systems are to be used with aftermarket upper control arms only
• Shocks Are Fully Serviceable. Lift Heights Indicated Are For A Stock Equipped Vehicle.
• Fits single rear wheel models only
• Requires recalibration of Advanced Driver Assistance Systems (ADAS) after install
• An iOS operated device is required to run ICON Intelligent Control app
• Included rear shocks are compatible with 0-1.5" of rear lift over stock
• GM 2500 HD models equipped with Max Trailering Package and GM 3500 HD require removal of top overload leaf

Manufacturer Description

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 6 system is comprised of CDEV equipped V.S. 2.5 Aluminum Series remote reservoir front and piggyback reservoir 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 2.5 Aluminum 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. The included ICON billet aluminum upper control arm kit is designed to improve overall performance with corrected front-end geometry, increased on-vehicle camber and caster adjustment, improved suspension component clearance, and when paired with the extended travel front shocks, increases wheel travel over the OEM configuration to maximize suspension performance. Additionally, replacing the OE ball joint with the serviceable and rebuildable ICON Delta Joint Pro HD allows for full bump and droop travel of the front suspension while eliminating bind. The included torsion keys install onto the factory torsion bars and allow for 2-3.5" of front lift height adjustment to allow for a level stance and larger, more aggressive wheel and tire fitment. ICON rear leaf packs provide improved ride quality while maintaining factory rear ride height. These full replacement leaf back lowers the rear spring rate approximately 20% compared to stock as well as shifts the overload transition point higher in the suspension travel to improve small bump compliance. 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.
