The ICON Stage 3 System takes all factors into account in order to provide you with a level stance, perfect steering geometry, and superb on or offroad handling characteristics. The simple, adjustable, abuse proof torsion keys will provide the height you require, while the Tubular Upper Control Arms not only deliver alignment correction, but also provide for a robust replacement that is sure to take substantially more abuse than the factory units. And to round it off, the 2.5" V.S. Series Piggyback shocks create a truck that is capable of handling nearly anything you can throw at it offroad, but also superb street manners.
