What is the benefit of double adjustable control arms?

Double adjustable control arms allow you to change the length of the arm at both ends. This makes it much easier to dial in your caster angle for proper alignment after lifting your vehicle, and you can often make these adjustments without removing the arms from the Jeep.

Do these control arms come with hardware?

The manufacturer's description does not specify if installation hardware is included. It is recommended to refer to the manufacturer's installation instructions for a complete list of included components and any additional hardware that may be required.

Can I reattach my factory brake lines to these control arms?

No, these control arms do not provide provisions for reattaching your front brake line brackets. You will need to plan for an alternative method to secure your brake lines.

About this part

Product Details

RockJock is known for making seriously tough suspension components for off-road vehicles. If you're lifting your 2018-2025 Jeep Wrangler or 2020-2025 Jeep Gladiator, you're going to need to adjust your caster angle to get the alignment right, and these double adjustable lower control arms are built for that job. They replace your factory arms and give you the adjustability you need to dial in your suspension after a lift.

These arms are CNC machined from strong 7075-T6 aluminum, which keeps them lightweight but incredibly robust. The real standout feature here is the patent-pending RockNut locking nut technology. This means you can adjust the length of the arms without having to remove either end from the vehicle, making alignment adjustments much simpler. They come equipped with RockJock's massive 2 1/2 inch Johnny Joints, which have huge 1 1/4 inch right and left-hand threads for maximum strength and adjustability. The arms are fully greasable, and they even have machined-in wrench flats to make adjustments even easier. They're finished with a clear anodize on the arms and gold zinc plating on the Johnny Joint ends.

Keep in mind that these control arms do not have provisions for reattaching your front brake line brackets. You'll want to plan for an alternative mounting solution for your brake lines. These are a substantial upgrade designed for serious off-road use and proper alignment after significant suspension modifications.
