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.

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.


  • Vehicle Fitment: Jeep Wrangler JK 07-18 – Comprehensive suspension upgrade designed to restore alignment, enhance stability, and eliminate common drivability issues.

  • CORE Advantage: Provides full suspension control by replacing all eight control arms and both track bars, eliminating wandering, bump steer, and instability caused by worn factory components.

  • Adjustability: Accommodates 0 to 6 inches of lift, allowing precise caster correction, axle centering, and pinion angle adjustments for optimized handling and tire longevity.

  • Construction: Heavy-duty steel tubing and polyurethane bushings for enhanced durability and ride quality.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

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 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!!

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!
