What is the benefit of double adjustable control arms?

Double adjustable control arms allow you to make alignment corrections, such as adjusting the pinion angle, without removing the arms from the vehicle. This makes the alignment process much quicker and easier, especially on lifted Jeeps.

Are these control arms greasable?

Yes, the Johnny Joints on these control arms are fully greasable. This allows you to maintain proper lubrication, which is essential for smooth operation and longevity, particularly in harsh off-road conditions.

What material are these control arms made from?

These control arms are CNC machined from 7075-T6 billet aluminum. This material is chosen for its high strength-to-weight ratio, providing a robust component that doesn't add excessive mass.

About this part

Product Details

Starting with the CNC machined 7075-T6 aluminum construction, these RockJock rear lower control arms are built for serious off-road use. The 7075-T6 aluminum offers a strong yet lightweight foundation, and the arms are designed to replace your factory components on the 2007-2025 Jeep Wrangler JK and JL models. These are double adjustable, meaning you can fine-tune your pinion angle and alignment without needing to remove the arms from the vehicle, which is a huge time saver when setting up a lifted Jeep.

What really sets these apart is the patent-pending RockNut locking nut technology. This system allows for easy adjustments using the machined-in wrench flats, and the massive 1 1/4 inch RH and LH threads on the 2 1/2 inch Johnny Joints provide a wide range of adjustment. The Johnny Joints themselves are fully greasable, ensuring smooth operation and longevity, even when subjected to mud, water, and grit. The arms come finished with a clear anodize on the aluminum and gold zinc plating on the joint ends for added corrosion resistance.

When you're lifting your Jeep, getting the pinion angle correct is critical for driveline longevity and smooth operation. These control arms make that adjustment straightforward. You'll want to refer to the manufacturer's installation instructions for the specific adjustment procedures and any other hardware that might be needed for your particular lift height.
