      Superior Off-road Performance

Specifically designed to be compatible with Ford Bronco model years 2021-Present, these control arms are meticulously engineered to provide exceptional flexibility, and superior on-road manners, making your off-road adventures remarkably more exciting and comfortable.

      Precision Engineered for Maximum Durability

      The Crawl Series Rear Upper Control Arms are crafted with meticulous attention to detail.

They feature the original Johnny Joints from Rock Jock 4x4 at both ends, delivering consistent, high-quality performance, even under the most challenging conditions.

      Ultimate Adjustability for Complete Control

      Experience the advantage of ultimate adjustability. Our Rear Upper Control Arms are threaded both left and right handed, enabling easy adjustment of your pinion angle while installed and can accommodate lifts from 0 to 6 inches. These arms, when used in conjunction with our adjustable lower control arms, allow for the precise re-centering of your rear axle and exact adjustment of the pinion angle.

For vehicles with lifts beyond 6 inches, please contact us for additional options and assistance.

      Two-Stage Powder Coating for Enhanced Durability

      All of our control arms undergo a rigorous two-stage powder coating process to maximize durability and resist corrosion. We begin with a zinc primer base to ensure maximum adherence, followed by a robust top coat in your choice of color. This process ensures a resilient and aesthetically pleasing finish, enhancing the durability and longevity of your control arms.

      Good

      Easy to install. Just pops like every other adjustable arm. You better have some mojo to tighten the adjustment nut down, otherwise it'll pop worse than popcorn.

      Core 4x4 Control Arms

      These are extremely strong control arms that are fully adjustable. They do exactly what they are designed to do. I do quite a bit of off-roading and they hold up well and increase flex very well. Would recommend these to anyone looking for control arms.

      Core 4x4

      This would have taken me a little over an hour to install if I had not bought a cheap set first. The first set I purchased ended up being made with the incorrect angles. After a day and a half of adjustments and loosening the entire suspension I had to return them. Core 4x4 are built and powder coated in the US so they take a little long to get but are worth the wait and the money. Their customer support answered the phone on a Saturday and gave me the starting measurements for the control arms per the set up on MY jeep. Great customer service and a great product.

      Solid buy

      These were simple to adjust and install. Once the bolts were broken loose on the stocks arms of course... Definitely an upgrade from stock, and a must have if you are doing a lift (I did either a 3" or 3.5", can't remember lol). Happy with this product.

      Beefy control arms. Allowed me to adjust the front and rear axles to their proper locations and differentials pinion angles after installing a 2.5" lift. Greaseable is nice.

      Great upgrade for our lifted jeep

      We have a 4 inch lift on our Jeep from the previous owners and they didn’t do all that I felt was needed for safety running 35 inch tires. This was a great kit for us and the way we will use the Jeep. I was able to install all the parts myself although I did have some rusty bolts to contend with. I had it professionally aligned after, and it’s driving fantastic now!
