This Cognito 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 also allowing for 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.
Cognito billet upper control arms feature 6061 aluminium construction, PTFE lined rodends, and Delta Joint, a hardcore high-angle ball joint that combines the durability of a ball joint with the performance of a traditional uniball.
