Upgrade Your Jeep Wrangler JK’s Suspension for Maximum Stability and Performance

Transform your Jeep Wrangler JK (2007-2018) with the Cruise Series 10-Piece Kit, a complete suspension overhaul designed to address common drivability issues, caster misalignment, and instability caused by worn-out factory components. Whether you're tackling daily commutes, rugged off-road terrain, or battling the dreaded death wobble, this kit provides precise axle centering, improved handling, and enhanced suspension geometry—all while maintaining a comfortable ride on the pavement.

What’s Included in the Kit?

  • Cruise Series Front Upper Control Arms (CRS-J-JK-FU2)
  • Cruise Series Front Lower Control Arms (CRS-J-JK-FL2)
  • Cruise Series Rear Upper Control Arms (CRS-J-JK-RU2)
  • Cruise Series Rear Lower Control Arms (CRS-J-JK-RL2)
  • Cruise Series Front Track Bar (CRS-J-JK-FTB1)
  • Cruise Series Rear Track Bar (CRS-J-JK-RTB1)

Key Features and Benefits

  • Complete suspension solution – Replaces all eight factory control arms and both track bars, restoring caster, pinion angle, and axle alignment for maximum stability, steering response, and tire longevity.
  • Eliminate common Jeep JK issues – Corrects suspension geometry to reduce death wobble, wandering, and following ruts in the road. Worn-out factory bushings and weak control arms contribute to poor handling—this kit solves those problems.
  • Fully adjustable for lifted vehicles – Accommodates 0 to 6 inches of lift, allowing precise alignment corrections, caster adjustments, and axle re-centering for a smoother ride. Custom solutions available for lifts over 6 inches.
  • Heavy-duty construction – Crafted from strong steel tubing, these components far surpass factory durability, ensuring long-term performance on and off the road.

Recommended Pairing

For an even more advanced suspension solution, pair this kit with the Cruise Series Front and Rear Sway Bar End Links (CRS-J-JK-ELS4) to further enhance handling, body roll resistance, and suspension articulation.

Durable Two-Stage Powder Coating

Each component undergoes a zinc primer base coat for corrosion resistance, followed by a top coat available in 10 colors for a personalized look.

Effortless Installation

Designed for direct bolt-on installation using factory hardware, with optional Grade 8 hardware kits available separately for rusted or stubborn bolts.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

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.

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.

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!

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 :) .

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.

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)
