Enhanced Performance and Control

Upgrade your Jeep Gladiator JT (2020-Present) with our Cruise Series Rear Control Arm Set, designed to provide superior handling, durability, and axle alignment correction. This set includes both rear upper and rear lower control arms, working together to re-center the rear axle and correct pinion angles, ensuring a smoother, more controlled driving experience both on and off-road.

What’s Included in the Kit?

  • Cruise Series Rear Upper Control Arms (CRS-J-JT-RU2)
  • Cruise Series Rear Lower Control Arms (CRS-J-JT-RL2)

Key Features and Benefits

  • Heavy-Duty Steel Construction – Built from high-strength steel tubing for maximum durability and impact resistance.
  • Adjustable for 0 to 6 Inches of Lift – Allows for precise pinion angle correction and axle re-centering after lifting your Gladiator.
  • Tapered Polyurethane Bushings – Absorb vibration and enhance responsiveness, providing a smoother ride than stock rubber bushings.
  • Complete Rear Axle Alignment Solution – When paired with our Cruise Series Rear Track Bar (CRS-J-JT-RTB1), this set provides full control over rear suspension geometry, eliminating driveline vibrations and rear-end instability.

Two-Stage Powder Coating

Each control arm undergoes a two-stage powder coating process for maximum corrosion resistance and long-lasting durability. Zinc primer base coat ensures protection from rust and environmental wear. Top coat available in 10 color options, allowing for customization to match your vehicle’s build.

Proudly Made in the USA

Manufactured in Orem, UT, our Cruise Series Rear Control Arm Set is built to strict quality standards, ensuring reliability, strength, and superior performance.

Optional Hardware Upgrade

  • The Cruise Series Rear Control Arms install using factory hardware.
  • For those dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately to simplify installation.

In Conclusion

The Cruise Series Rear Control Arm Set is a must-have upgrade for Gladiator JT owners looking to eliminate rear axle misalignment, improve stability, and optimize suspension performance.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

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.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

I wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.
