RockJock JL/JK Johnny Joint Control Arms Rear Upper Adjustable Pair

The rear upper control arms on your Jeep Wrangler, whether it's a JK or a JL, are critical for setting your pinion angle, especially after you've installed a suspension lift. These adjustable arms from RockJock are fabricated from tough 1.25-inch outer diameter, .188-inch wall DOM steel tubing, which is a strong choice for off-road components. They come equipped with RockJock's well-known Johnny Joint rod ends on both ends – one is a 2.5-inch joint, and the other is a 1.25-inch right-hand thread forged joint with a jam nut. This setup is designed to give you maximum articulation when you're out on the trail.

What makes these arms really useful is their adjustability. After you've installed a lift kit, you'll likely need to dial in your pinion angle to reduce driveshaft vibrations and wear. These arms let you do that precisely. Plus, if you decide to upgrade your lift height down the road, you won't need to buy new control arms; you can simply adjust these to accommodate the change. They're finished off with a semi-gloss black powder coat for durability, and the forged ends get a gold zinc plating to help keep corrosion at bay.
