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.

These control arms outperform factory components, providing superior durability, strength, and precision alignment for a smoother, more controlled driving experience.

What’s Included in the Kit?

  • Pair of Rear Lower Control Arms (CRS-J-WK-RL2)

Key Features and Benefits

  • Heavy-Duty Steel Construction – Built to withstand harsh conditions and deliver long-lasting performance.
  • Fully Adjustable Design – Allows for pinion angle correction and rear axle re-centering, accommodating lifts from 0 to 6 inches.

  • Recommended Pairing – For a complete rear suspension solution, pair with our Cruise Series Rear Upper Control Arms (CRS-J-WK-RU2) to fully correct alignment and optimize handling.

Optimized Rear Suspension Performance

Lifting your Jeep can misalign the rear axle, cause excessive tire wear, and create instability. Our adjustable Rear Lower Control Arms provide the necessary strength and flexibility to correct pinion angles, re-center the axle, and improve handling. When combined with our Rear Upper Control Arms, you gain full control over rear suspension geometry, reducing unnecessary stress on your drivetrain and enhancing overall ride quality.

Two-Stage Powder Coating for Maximum Durability

To ensure long-term performance and corrosion resistance, all components undergo a two-stage powder coating process: Zinc primer base coat – Provides rust protection. Durable top coat – Available in 10 colors, allowing you to personalize your suspension.

Made in the USA

Proudly manufactured in Orem, UT, using locally sourced materials to meet the highest quality standards.

Optional Hardware Upgrade

Designed for easy installation using factory hardware. If you're dealing with rusted or worn-out bolts, we offer optional Grade 8 hardware kits, available separately, for a hassle-free install.

In Conclusion

The Cruise Series Rear Lower Control Arms provide the strength, adjustability, and precision alignment your Jeep Grand Cherokee WK needs. Pair them with our Rear Upper Control Arms for a fully optimized rear suspension setup, eliminating instability and enhancing overall drivability.

Upgrade today and experience superior handling, durability, and off-road confidence!

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.

I met a couple of the Core 4x4 guys at the Salt Lake Offroad Expo and decided to try them out after noticing one of my control arm bushings was disintegrated. I called to discuss parts on Thursday and I was leaving for a trip on Saturday. These guys built my control arms and had them ready to be picked up Friday, 24 hours later. The parts seem to be great quality and they charged me nothing extra to have them painted. These guys were extremely helpful and without them my trip probably would have been cancelled. looking forward to testing out the arms on my next trip to Moab.

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.

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

Awesome control arms! My mechanic said “ your Jeep is pretty much bulletproof now.” And I just got the tier 1 arms! The people at the core 4x4 shop were really nice too. They were running behind on shipping, (which is understandable) so I decided to go pick it up because it was only an hour drive. They gave me a free $60 hardware kit for the inconvenience. Thanks core 4x4! You guys are awesome!!

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.
