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.

What's Included in the Kit?

  • Cruise Series front upper control arms (CRS-J-WJ-FU2)
  • Cruise Series front lower control arms (CRS-J-WJ-FL2)
  • Cruise Series rear lower control arms (CRS-J-WJ-RL2)
  • Mounting spacers (8)

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.
  • Tapered polyurethane bushings – Reduces vibrations, improves responsiveness, and outperforms factory rubber bushings.
  • Recommended pairing – For a complete suspension upgrade, pair with our Cruise Series Rear Upper Adjustable A-Arm (CRS-J-WJ-AA1) to fully optimize rear axle articulation and pinion angle correction.

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!

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

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.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

2001 Wrangler TJ- i have purchased all front/rear upper/lower control arms. Front track bar and rear track bar. Quality is excellent and extremely durable you can tell its built to last. Bent a bolt on the front track bar and called and spoke with Spence. He immediately sent me out new hardware plus some! Product is amazing but what really separates companies apart is their service and these guys are second to none. Thank you all!

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)
