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.

Optimized Control and Alignment for Lifted Vehicles

Upgrade your Jeep Grand Cherokee WJ (1999-2004) with the Cruise Series Front Upper Control Arms, engineered to correct alignment issues, optimize suspension geometry, and improve overall ride quality. Whether you're tackling off-road trails or daily driving, these arms deliver enhanced strength and precise adjustability, making them a superior replacement for factory components.

For the best results, we recommend pairing these with the Cruise Series Front Lower Control Arms (CRS-J-WJ-FL2). Together, these components fully re-center your axle, restore proper caster, and improve handling, reducing wandering, uneven tire wear, and steering instability.

What’s Included in the Kit?

  • Cruise Series Front Upper Control Arms (CRS-J-WJ-FU2)

Key Features and Benefits

  • Precise Adjustability – Designed to accommodate lifts from 0 to 6 inches, ensuring proper alignment after suspension modifications.
  • Enhanced Strength – Built from heavy-duty steel tubing for superior durability compared to factory parts.
  • Optimized Suspension Geometry – Corrects caster and pinion angle, reducing driveline vibrations and enhancing steering control.
  • High-Performance Polyurethane Bushings – Provides better responsiveness, reduced road noise, and improved suspension flex compared to rubber bushings.
  • Recommended Pairing – For full front-end suspension optimization, pair with the Cruise Series Front Lower Control Arms (CRS-J-WJ-FL2) to fully re-center the axle and maximize handling stability.

Full Caster Correction and Drivability Enhancement

Lifting your Grand Cherokee WJ changes the caster angle, which can cause steering instability, wandering, and uneven tire wear. These adjustable upper control arms allow you to fine-tune caster for improved high-speed stability and responsive steering. When paired with our Front Lower Control Arms (CRS-J-WJ-FL2), you get complete control over your axle placement and alignment, ensuring a smoother, more predictable ride.

Two-Stage Powder Coating

Our two-stage powder coating process ensures maximum durability and corrosion resistance: Zinc primer base coat for rust protection. Durable top coat available in 10 colors for customization and extra durability.

Made in the USA

Proudly manufactured in Orem, UT, our Cruise Series components are built with locally sourced materials, ensuring high-quality craftsmanship and superior performance.

Optional Hardware Upgrade

These control arms install using factory hardware, but for a smoother installation, we offer optional Grade 8 hardware kits, available separately.

In Conclusion

The Cruise Series Front Upper Control Arms provide precision alignment correction, improved durability, and enhanced driving comfort. Pair them with the Cruise Series Front Lower Control Arms (CRS-J-WJ-FL2) for complete suspension optimization, ensuring proper caster, axle centering, and steering stability. Upgrade your Jeep Grand Cherokee WJ today and enjoy better handling both on and off the road!

Hardware No Hardware or Complete Kit

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.

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)

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.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

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!!

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.
