RockJock JK Johnny Joint Adjustable Control Arms Front Upper Double Adjustable Greasable Pair

When you're installing a suspension lift on your Jeep Wrangler JK, you'll often need to adjust the pinion angle to get everything aligned correctly. This pair of front upper adjustable control arms from RockJock is designed to make that process much simpler. You get a pair of arms, each featuring RockJock's well-known Johnny Joint rod ends on one end and a formed steel fork with a jam nut on the other. These arms are built from 1 1/2 inch O.D. solid steel bar and finished in a semi-gloss black powder coat for durability.

The real advantage here is the double adjustable design. The threaded adjuster ends allow you to change the length of the control arm without removing it from the vehicle. This means you can dial in your pinion angle precisely after your lift is installed, and it also makes it easier to accommodate future lift height changes without needing to buy new control arms. The Johnny Joints themselves offer excellent flex, and they are greasable, so you can keep them well-lubricated for a long service life. These are a direct replacement for your stock front upper control arms.

To get the most articulation out of these control arms, consider adding the CE-9102JK Johnny Joint kit to your front differential. This setup will help ensure your Jeep can handle off-road obstacles with maximum wheel travel.
