All-Pro Off Road's new Upper A-Arm kit is constructed of 4130 Chromoly material. These arms are TIG welded, not MIG welded like competing brands. TIG welding keeps the heat between the weld and base, providing superior strength without weakening the surrounding material. Now featuring a top quality, teflon-lined 1.25" uni-ball that provides maximum articulation for the Upper A-Arm without binding up like the factory ball joint. These arms are designed to correct suspension geometry on lifted applications, and now have zerk fittings for easy bushing lubrication. Easy bolt-on installation with all hardware & Prothane bushings included. Powdercoated silver as shown.
