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.

Enhanced Performance and Control

Upgrade your Jeep Grand Cherokee ZJ’s suspension with our Cruise Series Rear Upper Control Arms, engineered for superior strength, adjustability, and long-term durability. Designed to accommodate 1993-1998 models, these control arms provide precise alignment correction, improved ride quality, and enhanced off-road performance.

What’s Included in the Kit?

  • Cruise Series Rear Upper Control Arms (CRS-J-ZJ-RU2)

Key Features and Benefits

  • Precision Adjustability – Designed to accommodate lifts from 0 to 6 inches, allowing for proper pinion angle correction and rear axle re-centering to optimize drivetrain performance.
  • Heavy-Duty Steel Construction – Crafted from strong steel tubing, these control arms provide the durability needed for extreme off-road conditions while maintaining on-road comfort.
  • Tapered Polyurethane Bushings – Reduces noise, vibration, and harshness (NVH) while delivering smoother suspension movement and enhanced responsiveness.
  • Recommended Pairing – For complete alignment correction, pair these Rear Upper Control Arms with our Cruise Series Rear Lower Control Arms (CRS-J-ZJ-RL2) to maximize stability and drivability.

Engineered for Maximum Adjustability

Our Rear Upper Control Arms allow for precise pinion angle adjustment, ensuring smooth drivetrain operation and minimized wear on tires and suspension components. When paired with Rear Lower Control Arms, they restore axle centering and proper geometry, making them an essential upgrade for lifted vehicles.

Two-Stage Powder Coating

Each control arm undergoes a two-stage powder coating process to maximize corrosion resistance and longevity. Zinc Primer Base Coat – Protects against rust and environmental damage. Durable Top Coat – Available in 10 color options, allowing you to personalize your suspension setup.

Proudly Made in the USA

Our Cruise Series Rear Upper Control Arms are manufactured in-house at our facility in Orem, UT, where we maintain full control over production and source high-quality domestic materials to ensure unmatched performance and reliability.

Optional Hardware Upgrade

Our control arms are designed for easy installation using factory hardware. However, if you’re dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately to ensure a hassle-free installation process.

In Conclusion

Invest in Cruise Series Rear Upper Control Arms for exceptional durability, improved suspension articulation, and a smoother ride both on and off-road.

Upgrade your Jeep Grand Cherokee ZJ today and experience enhanced alignment correction, better handling, and superior off-road performance!

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.

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 ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!

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.

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

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.
