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.

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👌🏽

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!

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 :) .
