What is the benefit of adjustable control arms after installing a lift kit?

Adjustable control arms allow you to correct your vehicle's pinion angle after installing a suspension lift. This helps to reduce vibrations and wear on your driveshaft and differential components, ensuring smoother operation and longer component life.

Do these control arms come with everything needed for installation?

These control arms are designed as a direct replacement for your stock front lower arms and include the Johnny Joint rod ends and skid plates. However, they must be used in conjunction with adjustable upper control arms, which are sold separately, to achieve proper alignment.

What kind of tires can I run with these control arms?

These arms are designed to work with 37-inch tires on stock-width axles when using wheels with a 4 1/2-inch backspace. If you plan to run larger tires, you may need to consider wider axles or wheel spacers.

About this part

Product Details

RockJock is known for making solid suspension components for Jeeps, and these front lower adjustable control arms are a prime example. If you've installed a suspension lift on your 2007-2017 Jeep Wrangler JK and need to dial in your pinion angle, these arms are what you're looking for. They're designed to replace your stock front lower arms and give you the adjustability needed to correct driveline angles after lifting your vehicle.

These arms are CNC machined from strong 6061-T6 billet aluminum and finished with a black anodized coating and machined accents, making them a good-looking addition to your Jeep. They feature RockJock's popular Johnny Joint rod ends on both ends, which offer a wide range of motion and durability. The arms are double-adjustable, meaning you can lengthen or shorten them using the right-hand and left-hand threaded rod ends. This adjustability is key for setting your pinion angle correctly after a lift. For added protection, they include bolt-on 4130 chromoly skid plates that can be replaced if damaged. These arms are a minimum of 3/8 inch longer than stock and are designed to work with 37-inch tires on stock-width axles with a 4 1/2-inch backspace wheel; larger tires might require wider axles or wheel spacers.

Keep in mind that these adjustable control arms must be used with adjustable upper control arms to achieve proper alignment. They are a direct replacement for your stock front lower arms, but the adjustability is where they really shine for lifted Jeeps.
