These direct-fit front upper control arms add strength, on-car adjustability and articulation flexibility to your stock-height or 'lifted' suspension Wrangler. They feature SPC's xAxis sealed flex joints mounted in forged rings at the frame ends to provide bind-free 'twist' between the frame and axle during off-road articulation. The dual-threaded adjuster and jam nuts make caster/pinion angle adjustments quick and easy without the need to disconnect the arms or mess with cams and slotted hole knock-outs. Main tube is 3/16" wall DOM steel for 'overkill' strength to handle large tires, low gearing, and big horsepower. California Residents WARNING
