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.

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last. I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days. If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

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 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.

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

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.

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.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.
