Why Builders Choose CORE 4X4

Warranty facts, not marketing language.

vs. MetalCloak

Their “lifetime” language refers to their service model. Actual parts warranty: 1 year. Ours: lifetime.

vs. Teraflex

Skip a maintenance interval? Their warranty voids. Ours doesn’t.

vs. Clayton Off Road

Clayton warrants their Johnny Joints for 90 days. We cover ours for life.

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.

What’s Included in the Kit?

  • Cruise Series front upper control arms – CRS-J-JL-FU2
  • Cruise Series front lower control arms – CRS-J-JL-FL2
  • Cruise Series rear upper control arms – CRS-J-JL-RU2
  • Cruise Series rear lower control arms – CRS-J-JL-RL2

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!

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.

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!!

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!
