The ICON 2011+ Chevy / GMC 2500HD / 3500 5" - 8" Suspension System - Torsion Relocation System (TRS) - Stage 3 System was engineered to offer superior ride quality, performance, component protection, and reliability all in one complete package. With over a year of development and testing our suspension system is sure to perform with the best on or off road handling and drivability. Included in this lift kit are components and features such as a heavy duty boxed sub-frame with integrated differential and transmission skid plates, precision CNC machined cast iron spindle knuckles, adjustable lift height, V.S. 2.5 Series shocks front & rear, rear lift blocks w/ built in bump stops, torsion bar relocation brackets, all 100% Made in the USA. ICON's TRS System allows the factory torsion bar to remain in the factory location giving the center of the vehicle maximum ground clearance. The Stage 3 GM 2500HD / 3500 5-8" system upgrades the 2.0 Aluminum Series shocks to V.S. 2.5 Series piggy back shocks giving you superior overall performance & handling compared to any other available suspension. We do offer additional upgraded stages that include out tubular uniball upper control arms that will increase your suspension travel almost 50%.

OPTIONAL CDC VALVE
The ICON CDC Valve is an externally adjustable valve that restricts oil flow into the reservoir creating 10 levels of compression damping force ranges. Controlling the amount of oil flow externally allows for optimally adjusting damping for varying terrain. With the addition of an ICON CDC Valve a different tune is required on the working piston to get the ride quality range of adjustment to softer than standard at the “S” setting and much firmer than standard at the “H” setting. The ICON CDC Valve piston is custom tuned per application with different valve stacks because not all shocks or applications are equal.
