Optimized Performance

Upgrade your Jeep Grand Cherokee WJ’s suspension with the Cruise Series Complete Control Arms Set, designed to maximize durability, improve handling, and restore proper alignment. This six-piece kit, specifically engineered for 1999-2004 WJ models, is an essential upgrade for those seeking better stability, reduced suspension wear, and enhanced drivability both on and off the road.

Key Features Benefits

  • Complete suspension overhaul – Replaces all six essential control arms to provide a comprehensive alignment and handling solution.
  • Heavy-duty steel construction – Built from high-strength steel tubing, ensuring durability and longevity in the toughest conditions.
  • Full adjustability – Designed to accommodate lifts from 0 to 6 inches, allowing for precise axle centering and optimal alignment.

Perfect Adjustability for Lifted Vehicles

Lifting your Grand Cherokee WJ alters suspension geometry, often leading to misalignment, handling instability, and premature component wear. Our fully adjustable control arms provide precise axle re-centering, improved drivability, and optimized pinion angles, reducing driveline vibrations and suspension stress.

Two-Stage Powder Coating

All our control arms undergo a two-stage powder coating process to ensure maximum durability and corrosion resistance. The first stage includes a zinc primer base coat for a protective barrier against rust, followed by a durable top coat available in 10 customizable colors to enhance aesthetics and provide long-lasting durability.

Made in the USA

Each Cruise Series Control Arm is proudly manufactured in Orem, UT, using locally sourced materials and precision engineering. By choosing our American-made components, you’re supporting top-tier manufacturing standards and high-quality craftsmanship.

Optional Hardware Upgrade

Our Cruise Series Complete Control Arms Set is designed for easy installation using factory hardware and the provided spacers. For those dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a hassle-free installation.

Final Thoughts

Upgrading to the Cruise Series Complete Control Arms Set means investing in superior handling, enhanced suspension durability, and precise alignment correction. Pair it with the Cruise Series Rear Upper Adjustable A-Arm (CRS-J-WJ-AA1) for a fully optimized suspension system. Upgrade today and take control of your Jeep Grand Cherokee WJ’s performance both on and off the road!

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!
