ICONs tubular steel rear lower link arms are a significant upgrade over the factory units due to increases in strength, adjustability, and performance. These components are made from CNC machined 1026 DOM steel and welded in - house, providing a major improvement over the construction of the stock units. This rear lower link arm kit features PTFE - lined FK rod ends and multi durometer, maintenance free bushings for reduced deflection, link arm length adjustment and increased articulation, 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.
