The ICON 2011-2016 Chevy/GMC 2500HD/3500  6-8" Stage 3 Torsion Relocation Suspension System is our top level system - engineered to offer superior ride quality, performance, component protection, increase suspension travel, 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, tubular uniball upper control arms, torsion bar relocation brackets, all Made in the USA. ICON's Torsion Relocation 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 6-8" system adds ICON tubular steel uniball upper control arms which increase the front suspension travel, giving you superior overall performance & handling compared to any other available suspension. Uniball upper control arms not only add suspension travel when paired with our V.S. 2.5 Series piggyback shocks, but strength and durability while at the same time improving alignment specifications.
