Eliminate Factory Suspension Issues Regain Full Control

From the factory, Jeep Wrangler JL models suffer from insufficient caster, leading to unstable steering, wandering, and poor highway manners. Lifting the vehicle only amplifies these issues, causing even more caster deficiency, axle misalignment, and increased driveline vibrations. The Cruise Series Control Arms Set is the ultimate solution to these problems, providing full adjustability to restore proper suspension geometry, re-center both axles, and improve handling. Whether you're upgrading for off-road capability or improved daily driving performance, this all-in-one kit ensures your suspension is dialed in for optimal stability and responsiveness.

Key Features and Benefits

  • Eliminates factory caster deficiency – Regain proper caster alignment for improved steering response, reduced wandering, and enhanced highway stability.
  • Re-centers front rear axles – Fully adjustable to correct axle shift caused by lifting, ensuring proper suspension geometry and better drivability.
  • Adjustable for lifts from 0 to 6 inches – Provides the flexibility to fine-tune suspension settings for different lift heights while preventing driveline vibrations and uneven tire wear.
  • Heavy-duty steel tubing construction – Built for maximum durability, ensuring strength in off-road conditions while maintaining on-road comfort.
  • Tapered polyurethane bushings for enhanced ride quality – Offers improved vibration dampening and responsiveness, outperforming traditional rubber bushings.

For lifts over 6 inches, contact us for custom solutions.

Recommended Pairing for a Complete Suspension Solution

For maximum stability and axle alignment, pair this kit with our Cruise Series Track Bar Kit (CRS-J-JL-TBK2), which includes front and rear adjustable track bars. Together, these components fully correct caster, steering geometry, and suspension alignment—eliminating issues like wandering, following ruts in the road, and death wobble.

Durable Two-Stage Powder Coating

Every control arm is powder-coated for long-lasting durability and corrosion resistance. A zinc primer base coat provides superior rust protection, while the durable top coat—available in 10 color options—adds extra durability and customization.

Proudly Made in the USA

Manufactured in Orem, UT, the Cruise Series Control Arms Set is designed to meet the highest American quality standards, ensuring long-term reliability.

Effortless Installation

Designed for direct bolt-on installation using factory hardware. If dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately for a seamless upgrade.

Final Thoughts

The Cruise Series Control Arms Set is the ultimate upgrade for restoring caster, re-centering axles, eliminating drivability issues, and optimizing suspension geometry. Whether you're looking to improve handling, eliminate death wobble, or upgrade for off-road performance, this complete control arm kit provides everything you need for a fully dialed-in suspension system. Upgrade today and transform your Jeep Wrangler JL’s ride quality, stability, and control!

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

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!

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.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!
