RockJock TJ/LJ Johnny Joint Adjustable Control Arms Rear Upper Double Adjustable Greasable Pair

If you've installed a suspension lift on your 1997-2006 Jeep Wrangler or LJ Unlimited, you'll likely need to adjust your pinion angle. These rear upper control arms from RockJock are designed to help you do just that. They feature RockJock's well-known Johnny Joint rod ends at both ends, which allow for a lot of flex, so your suspension can articulate freely over rough terrain.

What sets these apart is the double adjustable design. This means you can change the length of the arms while they're still bolted to your Jeep, making it much easier to set the correct pinion angle. Plus, because they're adjustable, you won't need to buy new control arms if you decide to change your lift height down the road. They're built from strong 1-inch by .156-inch wall DOM tubing and finished with a semi-gloss black powder coat for good looks and protection. They also come with greasable, Grade 8 mounting bolts, so you can keep those Johnny Joints well-lubricated.
