These control arms are made from carbon steel with polyurethane bushings. Eliminate wheel hop, steering wander and increase traction with an easy bolt on installation. 100% TIG welded for the ultimate in strength and appearance. These control arms are built with an offset to provide maximum tire clearance. When running larger tires they can rub against the stock control arms at full steering lock, our offset design eliminates this problem. You must to have these when you lift the vehicle 2" or more!
