ICONs billet aluminum rear upper link arms for the 2021-2023 Ford Bronco are a significant upgrade over the factory units due to increases in strength, adjustability, and performance. These links are made from CNC machined 6061 aluminum in-house and anodized for corrosion resistance, providing a major improvement over the construction of the stock units. This rear upper link arm kit features PTFE-lined FK rod ends for increased suspension articulation, reduced deflection, and on-vehicle link arm length adjustability using ICONs double adjuster system. Additionally, multi durometer bushings are installed that allow for noise free operation and maximum angularity without the need for periodic greasing and/or other maintenance. The quality rod ends and bushings featured in these link arms allow the vehicles suspension to function as intended, without the bushing bind that limits the vehicle in stock form. After the design phase was completed ICON engineers put these parts through the ICON1K real-world test cycle for a final stamp of approval.
