Complete Suspension Control for Maximum Performance

Upgrade your Jeep Grand Cherokee WJ (1999-2004) with the Cruise Series Total Control Kit, designed to eliminate steering instability, restore precise axle centering, and enhance overall handling. This all-in-one 7-piece suspension upgrade is built to significantly outperform factory components, ensuring smoother highway driving, superior off-road control, and long-term durability.

For a fully optimized suspension and steering setup, we recommend pairing this kit with the Cruise Series Rear Upper Adjustable A-Arm (CRS-J-WJ-AA1) to complete the rear suspension system.

Key Features Benefits

  • Full suspension overhaul – Includes 6 control arms and a front track bar, delivering a complete front and rear suspension upgrade.
  • Precise adjustability – Control arms adjust for lifts from 0 to 6 inches, ensuring proper axle alignment, pinion correction, and caster restoration.
  • Enhanced stability – The adjustable front track bar eliminates death wobble, wandering, and bump steer, keeping your front axle centered and secure. Adjustable from 2-6" of lift.
  • Heavy-duty construction – Built from high-strength steel tubing, ensuring superior durability for both on-road and off-road performance.
  • Advanced polyurethane bushings – Provides better responsiveness, reduced road noise, and improved suspension flex compared to rubber bushings.

Recommended Pairing

For a complete rear-end solution, pair this kit with the Cruise Series Rear Upper Adjustable A-Arm (CRS-J-WJ-AA1) to achieve full control over pinion angle and rear axle positioning.

Total Control Over Your Suspension and Steering

This kit is designed to eliminate common suspension issues like death wobble, axle misalignment, and instability at highway speeds. The front track bar and control arms work together to ensure proper caster correction, axle centering, and a more predictable driving experience. When paired with the Rear Upper A-Arm (CRS-J-WJ-AA1), this kit delivers unmatched suspension precision and long-term reliability.

Durable Two-Stage Powder Coating

All components undergo a two-stage powder coating process for maximum durability and corrosion resistance. A zinc primer base coat provides exceptional rust protection, while the durable topcoat, available in 10 colors, offers a long-lasting finish and customization options to match your build.

Made in the USA

Proudly manufactured in Orem, UT, this kit is built with locally sourced materials to ensure high-quality craftsmanship, superior performance, and long-term reliability.

Optional Hardware Upgrade

This kit installs using factory hardware, but for a smoother installation, we offer optional Grade 8 hardware kits, available separately.

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

Bought a new 2019 Ram 1500. Had bad rear wheel hop since new, got all four core 4x4 control arms and it fixed the issue. Thanks

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

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 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.

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.
