Rear Adjustable Control Arms (03-21 4Runner, FJ, GX)

Performance + durability of a race part. Manners + longevity of a stock part. The best of both worlds. Over the past 10+ years of building and breaking 4Runners, we have experienced a lot of different rear arm kits. There were lots of options on the market, but there just wasn't anything that checked off all the boxes. So we decided to build our own set of arms, using overkill steel tube, top quality machining, and the industry's gold-standard Johnny Joints®. Description: Thick-walled DOM steel: No more breaking and bending rear arms! 1.625in tube lowers, 1in tube uppers for the best compromise between strength and clearance throughout travel. Wrench flats for easy adjustment and torquing of the lock nuts. Powdercoated textured black with etched-in Opt logo. Adjustable, offset design: Correct your pinion angle to prevent premature u-joint wear and vibrations (if you have a lift then this applies to you). Move rear axle position for better tire clearance. Upper- Double adjustable
