ICONs tubular steel rear upper link arms for the 2020 - 2023 Jeep Gladiator and 2019 - 2023 Ram 1500 are a significant upgrade over the factory units due to increases in strength and suspension performance. These components are made from CNC machined and notched 1026 DOM steel and welded in - house, providing a major improvement over the construction of the stock units. This rear upper link arm kit features multi durometer bushings that allow for noise free operation, reduced deflection, and maximum angularity without the need for periodic greasing andor other maintenance.The quality 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.
