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.

Upgrade today and take full control over your Jeep’s rear suspension with the strength and precision of CORE 4X4’s industry-leading components!

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.

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 contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!
