Why Builders Choose CORE 4X4

Warranty facts, not marketing language.

vs. MetalCloak

Their “lifetime” language refers to their service model. Actual parts warranty: 1 year. Ours: lifetime.

vs. Teraflex

Skip a maintenance interval? Their warranty voids. Ours doesn’t.

vs. Clayton Off Road

Clayton warrants their Johnny Joints for 90 days. We cover ours for life.

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.

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
  • Cruise Series front track bar – CRS-J-WJ-FTB1

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.

Final Thoughts

The Cruise Series Total Control Kit (CRS-J-WJ-K7) delivers complete suspension stability and alignment correction. Pair it with the Cruise Series Rear Upper Adjustable A-Arm (CRS-J-WJ-AA1) for the ultimate suspension upgrade. Upgrade your Jeep Grand Cherokee WJ today and experience superior handling, precise axle alignment, and unmatched durability on any terrain!

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you’re running a non-standard setup, call us before ordering and we’ll confirm compatibility.

Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.

Yes, if you’ve done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you’d rather have it done.

Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.

Teraflex’s lifetime warranty voids if you miss a maintenance interval. MetalCloak’s actual parts warranty is 12 months — their “lifetime” language refers to their service program. No conditions here.

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.

I wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

The parts are a massive improvement over factory. I accidentally ordered the wrong endlinks and they helped me figure out the correct size and sent me new ones. Definitely an awesome store

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!
