These direct-fit, stock-length front lower control arms add strength, and articulation flexibility for your stock-height or 'lifted' suspension Wrangler. They feature SPC's xAxis sealed flex joints to provide bind-free 'twist' between the frame and axleduring off-road articulation. The main tube is 3/16" wall round DOM steel to provide strength and a knobby-tread-friendly shape to handle large tires, low gearing, and big horsepower. California Residents WARNING
