Performance and Control

Enhance your Jeep Gladiator JT’s performance on and off the road with our Cruise Series Rear Upper Control Arms. Designed for 2020-Present models, these control arms provide superior strength, precise adjustability, and durability over factory components, making them a critical upgrade for lifted vehicles.

Key Features and Benefits

  • Pinion Angle Correction – Adjustable design eliminates driveline vibrations by properly aligning the rear pinion angle.
  • Axle Re-centering – Works in conjunction with rear lower control arms to maintain optimal axle position.
  • Heavy-Duty Steel Construction – Built to withstand extreme off-road conditions while improving handling.
  • Tapered Polyurethane Bushings – Enhances ride quality by reducing vibrations and providing superior responsiveness.
  • Recommended Pairing – For a complete rear-end alignment solution, pair with our Cruise Series Rear Lower Control Arms (CRS-J-JT-RL2).

Precision Pinion Angle Alignment

One of the most overlooked but critical factors in suspension geometry is pinion angle alignment. When lifting a Jeep Gladiator, the pinion angle often becomes misaligned, leading to driveline vibrations, premature wear, and reduced drivetrain efficiency. Our adjustable Rear Upper Control Arms allow you to precisely correct the pinion angle, ensuring smooth operation and extending the life of drivetrain components.

When combined with our Cruise Series Rear Lower Control Arms (CRS-J-JT-RL2), this setup gives you full control over axle alignment and pinion correction, minimizing suspension stress and improving overall handling.

Two-Stage Powder Coating

Our control arms undergo a two-stage powder coating process for maximum durability and corrosion resistance. Zinc primer base coat – Provides superior rust protection. Durable top coat – Available in 10 color options, letting you customize your control arms to match your build.

Made in the USA

Proudly manufactured in Orem, UT, our Cruise Series Rear Upper Control Arms are built using locally sourced materials and strict quality control standards to ensure unmatched durability and performance.

Optional Hardware Upgrade

These control arms can be installed using factory hardware. However, if you're dealing with rusted or seized bolts, we offer Grade 8 hardware kits separately to streamline installation and ensure a secure fit.

Enhance your Jeep Gladiator JT’s handling, durability, and ride quality today with high-performance, American-made engineering.


  • Vehicle Fitment: Jeep Gladiator JT 20+ – Adjustable control arms improve rear axle alignment, suspension geometry, and driveline performance.

  • CORE Advantage: Corrects pinion angle to eliminate driveline vibrations, reducing wear on U-joints and improving ride quality.

  • Adjustability: Designed for 0 to 6 inches of lift, allowing precise pinion angle tuning and axle re-centering for lifted applications.

  • Construction: Heavy-duty steel tubing with tapered polyurethane bushings for increased durability, vibration absorption, and smoother articulation.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

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.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

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.

Very beefy items for a very reasonable price.  Personally have CORE rear track bar and all upper control arms for my 04 Jeep TJ.  Had a slight issue with control arm length and they went above and beyond to swap jam nuts to get me where I needed to be.  Really have to appreciate a company like this.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.
