Engineered for Superior Durability

Each control arm is purpose-built to withstand extreme conditions while delivering reliable performance. The lower control arms are constructed from 1.75” OD DOM tubing with a 5/16” wall thickness for maximum strength and stability, while the upper control arms feature 1.5” OD DOM tubing with the same robust wall thickness. Equipped with Johnny Joints at both ends, these control arms offer unparalleled articulation, flexibility, and long-lasting performance. The front upper control arms feature a U-bracket at the axle end for seamless integration with factory bushings.

Optimized Adjustability for Perfect Suspension Geometry

Designed to accommodate lifts from 0 to 6 inches, the Crawl Series Control Arms allow you to fine-tune your suspension for precise alignment correction, axle centering, and optimal pinion and caster angles. By combining all 8 control arms, this kit ensures a fully dialed-in suspension setup for superior handling and performance. For lifts beyond 6 inches, custom solutions are available—just contact us for assistance.

Two-Stage Powder Coating for Maximum Protection

Our control arms undergo a meticulous two-stage powder coating process for superior durability and corrosion resistance. A zinc primer base coat provides robust rust protection, while a durable top coat in your choice of 10 vibrant colors adds long-lasting protection and a personalized touch to your Gladiator.

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you're running a non-standard setup, call us before ordering and we'll confirm compatibility.

Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.

Yes, if you've done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you'd rather have it done.

Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.

Teraflex's lifetime warranty voids if you miss a maintenance interval. MetalCloak's actual parts warranty is 12 months — their "lifetime" language refers to their service program. No conditions here.

I want to take the time to share my experience with Core 4x4. I have a 2004 Jeep Wrangler and was looking to upgrade some suspension parts. I went with Core 4x4 upper & lower adjustable control arms and a front adjustable track bar. Everything arrived quickly, and right out of the box I was impressed with the quality and craftsmanship. I had a few questions during installation (measurements and torque specs), and I spoke with Korby on a couple of occasions. Not only did he send me detailed instructions, but he also shared an installation video specific to the part and vehicle I was working on, something you don’t get from many companies. The control arms fit perfectly, look great, and perform exactly as I hoped. I did run into an issue with the front track bar touching the front diff. When I reached out, Korby had me send pictures and then immediately offered two solutions: his bar guy could make a different bend and send it out to me, or I could get a full refund. His response honestly blew me away. As much as I wanted to run the Core 4x4 track bar, I chose the refund. Korby sent me a prepaid shipping label right away, no hassle. My experience with Core 4x4 has been excellent. Korby was extremely understanding, communicative, and helpful every step of the way. The parts I received were high quality, and the customer service was second to none. I would absolutely recommend Core 4x4 10 out of 10 times and will be using them again. Just a great American company with awesome people who truly care about their customers. Thank you Korby, and thank you Core 4x4!

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!
