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!

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.

Phenomenal company - very rare to come by in the automotive industry. Also very impressing. Let me start here. I got a set of yellow sway bar end links for my 19 ram DT (new body style) and let me tell you, I’m hooked. For numerous reasons. One the craftsmanship behind the product is unmatched for sure for without breaking the bank. 2ndly, they stand behind their product. Had a very minor issue and it was resolved in a blink of an eye!!! Insane. Just because of what i listed above i will forever spend my money with core 4x4! And i think you should too! I have no affiliation at all with this company besides being a consumer. I will be ordering my yellow UCAs and the rest of my rear suspension from them here shortly! Korby on the other hand. The representative that helped me went above and beyond FAST. I hung up the phone with him, and with in no lie 3 minutes he was calling back with an answer. GREAT GREAT GREAT customer service, Korby you and core 4x4 are what give us hope in the car community! With much love and great health to you all!!

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

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.
