This ICON billet aluminum upper control arm kit is designed to improve the overall performance of the new 2021-UP Ford Bronco with corrected front-end geometry, increased camber and caster adjustment, and improved suspension component clearance. Constructed of CNC machined 6061 billet aluminum utilizing a hybrid H-beam cross-section that is light-weight and resists bending forces better than tubular arms. Replacing the OE ball joint with the all-new, serviceable, and rebuildable ICON Delta Joint PRO allows for full bump and droop travel of the front suspension while eliminating bind. FK Rod End 3/4 Inch 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. Comes with all components and hardware necessary for a complete install, these billet UCAs are the perfect front end upgrade for the 2021-UP Ford Bronco.
