These direct-fit, stock-legth rear lower control arms add strength and articulation flexibility to your stock-height or 'lifted' Wrangler. They feature SPC's xAxis sealed flex joints at one end to provide bind-free 'twist' between the frame and axle during off-road articulation. The main tube is 3/16" wall round DOM steel to provide strength to handle large tires, low gearing, and big horsepower. California Residents WARNING
