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.

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've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store

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.
