Optimized Steering and Stability

Upgrade your Jeep Wrangler TJ/LJ’s handling and stability with the Cruise Series Front Control Arm Set, engineered for 1997-2006 models. This kit includes both Front Upper Control Arms (CRS-J-TJLJ-FU2) and Front Lower Control Arms (CRS-J-TJLJ-FL2), delivering superior strength, caster correction, and alignment precision. Whether tackling off-road terrain or driving at highway speeds, this set eliminates wandering, rut tracking, and steering instability, giving you a smoother, more controlled ride.

Key Features and Benefits

Corrects Caster Angle Deficiencies – Restores proper caster geometry, preventing wandering, rut tracking, and unpredictable steering at high speeds.
Full Front Axle Alignment Re-Centering – Works together to keep your axle properly positioned for better handling and suspension longevity.
Adjustable for 0 to 6 Inches of Lift – Allows precise suspension tuning for lifted Jeeps. Contact us for custom solutions beyond 6 inches.
Durable Steel Construction – Heavy-duty steel tubing provides maximum strength and impact resistance.
Recommended Pairing – For complete stability, pair with our Cruise Series Front Track Bar (CRS-J-TJLJ-FTB1) to keep your axle centered and eliminate bump steer.

Restore Control and Driving Confidence

Factory control arms often fail to maintain proper caster when lifting a Jeep, leading to unstable steering and premature tire wear. Our adjustable Front Control Arms restore optimal caster angles, ensuring:

Enhanced directional stability
Tighter handling
Smoother highway cruising

Two-Stage Powder Coating

Each control arm undergoes a two-stage powder coating process for superior corrosion resistance: Zinc primer base coat provides rust protection. Top coat available in 10 colors, allowing you to customize your suspension components.

Made in the USA

Every Cruise Series component is proudly manufactured in Orem, UT. We maintain complete control over design, production, and quality assurance, ensuring long-lasting durability and reliability.

Optional Hardware Upgrade

These control arms can be installed using factory hardware.
For rusted or stubborn bolts, we offer Grade 8 hardware kits separately to make installation seamless and hassle-free.

For the best results, pair with our Front Track Bar (CRS-J-TJLJ-FTB1) for complete front-end alignment and stability.

Upgrade today and experience true suspension control!

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

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 :) .

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that. Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

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!!

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

Great Experience. I wanted to make changes to my order and Korby was more than willing to work with me to get everything corrected. Hope to deal with these guys again in the future.
