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!

Not sure where to start, Products or Service or Warranty. Products: I found Core4x4 through a very respected YouTuber in the Jeeping community. I purchased an entire set of Core4x4 Control Arms three years ago and have beat the daylights out of them and they are still in great condition. Now, I purchased another Jeep, this time for my daughter and bought yet another set of Control Arms because I know that these things can take a beating and stand up to it. I plan on replacing more parts on this TJ and my JL and will continue to buy from Core4x4. Service: This isn't some huge name conglomerate that treats you like you're just another customer. They are quick with responses and will always make things right should something be a problem. Oh and the quickness in which they ship their products is unmatched. I bought these CAs for my TJ on Thursday, I received them on Monday. Most other manufacturers will tell you weeks, they had them to me in 2 shipping days. Warranty: Seriously, a lifetime warranty? Yes please. Nothing more to say. I can't say enough about how great of a company this is. I've even spoken to the owner through email a few years back on some questions that I had. Support small American built businesses. P.S. Core 4x4, feel free to make me an ambassador and send me some swag :) .

Beefy parts made and painted well, very fair pricing for what you get, and fantastic customer service to boot. Easily my favorite place to get suspension parts.

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last. I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days. If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

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!!

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.

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!!

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

Core 4x4 has outstanding products at a fair price and unmatched customer service. When you call Korby, it's like talking with a friend. Very cool and helpul! I ordered some custom control arms, but from the wrong product line and they were super cool about returning them and upgrading to a better "Crawl" series. Only charged the difference between the two products. They paid all the return shipping and sent the uprgaded arms super quick. It was only a couple days. Awesome!! I couldn't be happier with the transaction👍🏼 Also, these control arms are stout and take a beating. I run heck out my Jeep in the rocks and desert. No problems whatsoever. Thanks Core 4x4, ya'll are welcome at my campfire anytime! Jake T. Pleasant Hill, Or.
