ICON 2019-2023 GM 1500, 1.5-3.5" LIFT, STAGE 2 SUSPENSION SYSTEM, TUBULAR UCA

This system features upper control arms with ICON's patented Delta Joint. The Delta Joint is a heavy-duty high angle ball joint that combines the durability of a ball joint with the performance characteristics of a traditional uniball. While the industry standard uniball does a great job of allowing the control arms of a vehicle to articulate with little bind, they do have an inherent weakness that leaves more to be desired when used in a daily driven application - exposure to the elements. The Delta Joint features a zinc plated housing providing the first layer of corrosion resistance, while a tough grease seal keeps potentially harmful elements out of the inner workings of the joint. Metal on metal construction and a greaseable design increase the longevity of the Delta Joint while at the same time allowing for noise-free operation. What makes the Delta Joint unique is that it brings the best of both worlds to ICON upper control arms with features that make it more robust than a uniball, and at the same time capable of greater angularity than a typical ball joint.

TECH NOTE: Recommend replacing OE rear blocks on Silverado 1500 Trail Boss and Sierra 1500 AT4 models with 1" rear blocks if level stance is desired. See ICON part numbers 51001 and 52050.
