These upper control arms feature 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 greasable 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.

This ICON billet aluminum upper control arm kit is designed to improve the overall performance of the 2019-2026 GM Silverado/Sierra 1500 pickup or 2021-2026 GM SUV with corrected front-end geometry, adjustable camber and caster, and improved suspension component clearance. These are constructed of CNC machined 6061 billet aluminum merging light weight with high strength properties. Replacing the OE ball joint with the available ICON Delta Joint allows for full bump and droop travel of the front suspension while eliminating bind. FK Rod End 7/8” Heim joints provide precise and smooth function throughout the range of travel while ICON’s signature double adjuster sleeve allows for on-vehicle camber and caster adjustment. Included with all components and hardware necessary for a complete install, these billet UCAs are the perfect upgrade for the 2019-2026 GM 1500 pickup truck or 2021-2026 GM SUV.
ICON billet upper control arms feature 6061 aluminium construction, PTFE lined rodends, and ICON’s Delta Joint, a hardcore high-angle ball joint that combines the durability of a ball joint with the performance of a traditional uniball.
