Perfect Adjustability for Lifted Vehicles

Lifting your Grand Cherokee WJ alters suspension geometry, often leading to misalignment, handling instability, and premature component wear. Our fully adjustable control arms provide precise axle re-centering, improved drivability, and optimized pinion angles, reducing driveline vibrations and suspension stress.

Two-Stage Powder Coating

All our control arms undergo a two-stage powder coating process to ensure maximum durability and corrosion resistance. The first stage includes a zinc primer base coat for a protective barrier against rust, followed by a durable top coat available in 10 customizable colors to enhance aesthetics and provide long-lasting durability.

Made in the USA

Each Cruise Series Control Arm is proudly manufactured in Orem, UT, using locally sourced materials and precision engineering. By choosing our American-made components, you’re supporting top-tier manufacturing standards and high-quality craftsmanship.

Optional Hardware Upgrade

Our Cruise Series Complete Control Arms Set is designed for easy installation using factory hardware and the provided spacers. For those dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a hassle-free installation.

Final Thoughts

Upgrading to the Cruise Series Complete Control Arms Set means investing in superior handling, enhanced suspension durability, and precise alignment correction. Pair it with the Cruise Series Rear Upper Adjustable A-Arm (CRS-J-WJ-AA1) for a fully optimized suspension system. Upgrade today and take control of your Jeep Grand Cherokee WJ’s performance both on and off the road!

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

upper control arms look great and went on easy.. only reason I gave 4 stars and not 5 is because of a shipping issue which put my build a week behind. The issue was resolved quickly and painlessly, great customer service. Only time will tell how control arms perform but they look great and like they will go above and beyond control arm demand.

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.
