Optimized Rear Suspension Control

Upgrade your Jeep Wrangler TJ or LJ (1997-2006) with the Cruise Series Rear Upper Control Arms, designed to correct pinion angle, recenter the rear axle, and eliminate driveline vibrations. These control arms provide greater strength and adjustability over stock components, making them a must-have upgrade for lifted Jeeps looking to improve handling and drivetrain longevity.

What’s Included in the Kit?

  • Cruise Series Rear Upper Control Arms (CRS-J-TJLJ-RU2)

Key Features and Benefits

  • Pinion Angle Correction – Properly adjusts pinion angle to eliminate driveline vibrations and reduce wear on drivetrain components.
  • Rear Axle Recentering – Ensures accurate axle alignment to maintain stability and handling after lifting your Jeep.
  • Heavy-Duty Construction – Built from heavy-duty steel tubing for unmatched durability in on- and off-road conditions.
  • Polyurethane Bushings – Provides superior responsiveness, vibration absorption, and longevity over standard rubber bushings.
  • Recommended Pairing – For complete rear-end suspension alignment and axle centering, pair with our Cruise Series Rear Lower Control Arms (CRS-J-TJLJ-RL2).

Precision Adjustability

Our fully adjustable Rear Upper Control Arms are engineered to fine-tune pinion angle and re-align the rear axle. With a range supporting 0 to 6 inches of lift, they provide crucial adjustments to optimize handling and drivetrain function. If your lift exceeds 6 inches, contact us for additional options.

Two-Stage Powder Coating

For maximum durability and corrosion resistance, all control arms undergo a two-stage powder coating process: Zinc primer base coat – Provides rust protection. Durable top coat – Available in 10 customizable colors for a long-lasting, stylish finish.

Made in the USA

Proudly manufactured in Orem, UT, our Cruise Series components support American craftsmanship and are built to the highest performance and durability standards.

Optional Hardware Upgrade

Installation is straightforward using factory hardware, but for those dealing with rusted or seized bolts, we offer optional Grade 8 hardware kits, available separately for a seamless installation process.

In Conclusion

Upgrading to the Cruise Series Rear Upper Control Arms ensures pinion angle correction, driveline vibration elimination, and superior rear axle stability. Pair them with our Cruise Series Rear Lower Control Arms (CRS-J-TJLJ-RL2) for a complete rear suspension upgrade.

Enhance your Jeep Wrangler TJ or LJ’s drivability and durability today!

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 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!

I just finished installing the Peak 2.0 Front Suspension system with the Core 4x4 Blue Tacoma Rear Suspension system on my 2024 TRD Offroad Premium Tacoma. The two upgraded suspension systems really made a difference in how the ride feels, whether we’re off-road or on the road. A big thank you to Korby and the team at Core 4x4 for their support and for getting the shipping sorted out so quickly!

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.

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.
