SKU: K78201


The ICON 2011-2016 Chevy/GMC 2500HD/3500 6-8" Stage 1 Torsion Drop Suspension 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 great on or off road handling and drivability. System components and features include 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 front with 2.0 Aluminum Series rear shocks, rear lift blocks w/ built in bump stops, all Made in the USA. Additional stages are available that include 2.5 Series piggyback shocks front and rear, uniball upper control arms, and the Torsion Relocation Bracket Kit (go to 6-8" Suspension Systems w/ Torsion Relocation System) that keeps the factory torsion bars mounted in the stock location.

STAGE 2: System upgrades the smooth body shocks to V.S. 2.5 Series piggyback reservoir shocks giving you superior overall performance & handling compared to any other available suspension.

STAGE 3: 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 add strength and durability while improving alignment specifications
