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!

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!
