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.

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.

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!

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

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.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.
