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.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

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.

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!
