The ICON 2011-2016 Chevy/GMC 2500HD/3500 6-8" Stage 3 Torsion Relocation Suspension System is ICON's top-level system, engineered to offer superior ride quality, performance, component protection, increased suspension travel, and reliability in one complete package. With over a year of development and testing, this suspension system is designed to perform with the best on or off-road handling and drivability. Included components and features are 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 with built-in bump stops, tubular steel Delta Joint upper control arms, and torsion bar relocation brackets. 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 superior overall performance & handling compared to any other available suspension. Uniball upper control arms not only add suspension travel when paired with the V.S. 2.5 Series piggyback shocks but also add strength and durability while improving alignment specifications. Made in the USA.
