Improve Handling Restore Alignment

Upgrade your Jeep Wrangler TJ/LJ’s suspension with our Cruise Series Front Upper Control Arms, engineered for 1997-2006 models. These control arms provide superior strength and adjustability, allowing you to correct axle alignment, improve handling, and enhance ride quality for both on-road and off-road driving.

Key Features and Benefits

  • Optimized Caster Correction – Adjustability ensures proper caster angles, reducing wandering and rut tracking at highway speeds.
  • Adjustable for 0 to 6 Inches of Lift – Allows for precise front axle centering and alignment when lifting your Jeep.
  • High-Strength DOM Tubing – Built from heavy-duty steel tubing, delivering maximum strength and durability.
  • U-Bracket Axle Mount – Attaches securely to the factory axle-side bushing, ensuring long-lasting stability.
  • Recommended Pairing – Pair with our Cruise Series Front Lower Control Arms (CRS-J-TJLJ-FL2) for full axle alignment and complete caster correction.

Restore Alignment Improve Handling

When lifting your Jeep, factory control arms fail to maintain proper caster—leading to unstable steering and excessive tire wear. Our adjustable Front Upper Control Arms restore proper geometry, ensuring your Jeep tracks straight, feels stable at speed, and handles confidently both on and off the trail.

Two-Stage Powder Coating

Each control arm undergoes a two-stage powder coating process for maximum durability and corrosion resistance. Zinc primer base coat – Protects against rust and environmental wear. Durable top coat – Available in 10 colors for a customized suspension look.

Made in the USA

Every Cruise Series component is manufactured in Orem, UT, ensuring strict quality control and unmatched durability.

Optional Hardware Upgrade

These control arms are designed for installation using factory hardware. If you’re dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately for a seamless install.

 

Each rebuild kit includes all necessary components to replace and restore wearable parts.

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

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.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4
