RockJock TJ/LJ/XJ/MJ Johnny Joint Adjustable Control Arms Front Upper Adjustable Greasable Pair

When you're working on the front suspension of your Jeep Cherokee, Comanche, Grand Cherokee, or Wrangler, these adjustable upper control arms from RockJock are a solid choice. What you get in this pair is a set of two upper control arms, each built with a heavy-wall DOM tubing construction and featuring RockJock's well-known Johnny Joint at the frame end and a fork-style joint at the axle end. These arms are designed to be a direct replacement for your stock front upper control arms, but with the added benefit of adjustability.

The adjustability built into these arms is a real game-changer, especially if you've lifted your Jeep or plan to. It allows you to precisely dial in your pinion angle and caster angle, which is crucial for proper driveline alignment and steering geometry after a lift. This means you can accommodate different lift heights without needing to buy new control arms down the road. They're finished in a semi-gloss black powder coat for durability and come with greasable, Grade 8 mounting bolts.

It's worth noting that RockJock also offers a conversion kit to add Johnny Joints to the differential housing itself, which can be a good upgrade to consider at the same time you're installing these control arms.
