ICON*s billet aluminum rear upper link arms for the 2022-2023 Toyota Tundra, 2023 Toyota Sequoia, and 2024 Toyota tacoma 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 ICON*s 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 vehicle*s 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. ICON billet trailing arms are light, strong, and engineered to improve off-road ride quality. Built with CNC machined 6061 aluminum, they feature PTFE-lined rod ends, replaceable nylon rock sliders for protection, and on-vehicle adjustment.
