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.

Performance and Comfort

Upgrade your vehicle’s handling, stability, and durability with the Cruise Series Front Control Arm Set, specifically designed for Jeep Grand Cherokee WJ models (1999-2004). This set includes both Front Upper (CRS-J-WJ-FU2) and Front Lower (CRS-J-WJ-FL2) Control Arms, delivering a significant improvement over factory parts for both on-road comfort and off-road control.

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)
  • Mounting Spacers (4)

Key Features and Benefits

  • Increased Strength and Durability – Built from heavy-duty steel tubing, these control arms provide superior resistance to flex and wear.
  • Precise Adjustability – Fully adjustable to accommodate lifts from 0 to 6 inches, ensuring proper alignment and axle centering.
  • Tapered Polyurethane Bushings – Engineered for improved stability, responsiveness, and ride quality compared to factory rubber bushings.
  • Recommended Pairing – For a complete front-end suspension upgrade, pair with the Cruise Series Front Track Bar (CRS-J-WJ-FTB1).

Optimized Caster Alignment and Handling

Lifting a Jeep Grand Cherokee WJ without correcting caster angles can lead to unstable steering, wandering at highway speeds, and poor handling. Our Front Control Arm Set allows for precise alignment correction, ensuring smooth tracking and predictable steering—whether you're on the road or hitting the trails.

When combined with our Cruise Series Front Track Bar, you achieve a fully dialed-in suspension system, ensuring maximum stability and axle control.

Two-Stage Powder Coating

To provide maximum protection against rust and corrosion, our control arms undergo a two-stage powder coating process: Zinc Primer Base Coat – Forms a corrosion-resistant barrier. Durable Top Coat – Available in 10 color options for added protection and customization.

Made in the USA

All Cruise Series components are proudly manufactured in Orem, UT. By sourcing our materials locally and overseeing every step of the production process, we ensure unmatched quality and durability.

Optional Hardware Upgrade

  • Our Front Control Arm Set installs using factory hardware with the necessary spacers included.
  • For rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a smooth, hassle-free installation.

In Conclusion

Upgrading to the Cruise Series Front Control Arm Set means eliminating steering instability, regaining proper caster alignment, and improving both ride quality and durability.

For the best possible front-end suspension setup, pair these control arms with our Cruise Series Front Track Bar (CRS-J-WJ-FTB1).

Upgrade today and experience the difference in control, stability, and handling 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.

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.

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

I have bought a bunch of sets of arms, track bars and even had custom work done by Core 4x4. Just yesterday, Spence and Cam delivered an awesome cross member they designed and built for me! All of their products have been exceptional! I have personally seen their progression with design changes/updates. They truly take pride in their work and products. Quality control is second to none! They’ve also helped me diagnose issues with different jeeps I’ve had, as well as Dodge/Rams. These guys know their stuff! Really! I trust them whole heartedly and absolutely love their products/quality of work! I’ve referred many people, and will always continue to do so. Keep up the good work Core4x4!

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.
