Optimized Control and Alignment for Lifted Vehicles

Upgrade your Jeep Grand Cherokee WJ (1999-2004) with the Cruise Series Front Upper Control Arms, engineered to correct alignment issues, optimize suspension geometry, and improve overall ride quality. Whether you're tackling off-road trails or daily driving, these arms deliver enhanced strength and precise adjustability, making them a superior replacement for factory components.

For the best results, we recommend pairing these with the Cruise Series Front Lower Control Arms (CRS-J-WJ-FL2). Together, these components fully re-center your axle, restore proper caster, and improve handling, reducing wandering, uneven tire wear, and steering instability.

Key Features and Benefits

  • Precise Adjustability – Designed to accommodate lifts from 0 to 6 inches, ensuring proper alignment after suspension modifications.
  • Enhanced Strength – Built from heavy-duty steel tubing for superior durability compared to factory parts.
  • Optimized Suspension Geometry – Corrects caster and pinion angle, reducing driveline vibrations and enhancing steering control.
  • High-Performance Polyurethane Bushings – Provides better responsiveness, reduced road noise, and improved suspension flex compared to rubber bushings.
  • Recommended Pairing – For full front-end suspension optimization, pair with the Cruise Series Front Lower Control Arms (CRS-J-WJ-FL2) to fully re-center the axle and maximize handling stability.

Full Caster Correction and Drivability Enhancement

Lifting your Grand Cherokee WJ changes the caster angle, which can cause steering instability, wandering, and uneven tire wear. These adjustable upper control arms allow you to fine-tune caster for improved high-speed stability and responsive steering. When paired with our Front Lower Control Arms (CRS-J-WJ-FL2), you get complete control over your axle placement and alignment, ensuring a smoother, more predictable ride.

Two-Stage Powder Coating

Our two-stage powder coating process ensures maximum durability and corrosion resistance: Zinc primer base coat for rust protection. Durable top coat available in 10 colors for customization and extra durability.

Made in the USA

Proudly manufactured in Orem, UT, our Cruise Series components are built with locally sourced materials, ensuring high-quality craftsmanship and superior performance.

Optional Hardware Upgrade

These control arms install using factory hardware, but for a smoother installation, we offer optional Grade 8 hardware kits, available separately.

 

  • Vehicle Fitment: Jeep Grand Cherokee WJ 99-04 – Restores proper suspension geometry, enhances handling stability, and eliminates steering issues caused by improper caster alignment in lifted vehicles.

  • CORE Advantage: Corrects caster angle and re-centers the axle to reduce wandering, improve steering precision, and prevent uneven tire wear, ensuring a smoother and more controlled ride.

  • Adjustability: Fully adjustable to accommodate lift heights from 0 to 6 inches, allowing precise caster correction, pinion angle adjustments, and improved drivability on-road and off-road.

  • Construction: Built from heavy-duty steel tubing with high-performance polyurethane bushings, providing increased strength, responsiveness, and long-term durability over factory components.

  • 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.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

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.

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.

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.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

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! 👍👍
