Why Builders Choose CORE 4X4

Warranty facts, not marketing language.

vs. Teraflex

Skip a maintenance interval? Their warranty voids. Ours doesn’t.

vs. Clayton Off Road

Clayton warrants their Johnny Joints for 90 days. We cover ours for life.

Upgrade Your Jeep Wrangler JL’s Suspension and Steering Performance

Upgrade your Jeep Wrangler JL (2018-Present) with the Cruise Series 16-Piece Kit, a complete hard-component suspension and steering upgrade designed to eliminate common Jeep suspension issues and provide unmatched performance on and off the road.

Key Features and Benefits

  • Eliminates steering suspension issues – Corrects caster angle deficiencies, axle misalignment, and improper suspension geometry, eliminating wandering, rut-following, and instability after lifting your Jeep.
  • Reduces or eliminates death wobble – The combination of adjustable track bars and control arms improves front-end stability, eliminating the loose and unstable feel that contributes to death wobble.
  • Heavy-duty steering performance – The 2.5-ton aluminum steering kit delivers unmatched precision and durability, reducing steering play and providing more responsive handling.
  • Complete suspension control – Fully adjustable control arms and track bars allow for precise axle centering, pinion correction, and suspension tuning for lifts from 0 to 6 inches.

  • Built for any terrain – Designed for both daily driving and extreme off-road conditions, ensuring consistent, reliable performance in any environment.

Two-Stage Powder Coating for Maximum Durability

All components in the Cruise Series 16-Piece Kit undergo a two-stage powder coating process for superior corrosion resistance. A zinc primer base protects against rust, while the top coat is available in 10 colors, allowing you to customize your suspension setup.

Proudly Made in the USA

Manufactured in Orem, UT, this kit is built to the highest standards of American craftsmanship, ensuring superior durability, strength, and precision engineering for long-lasting performance.

Optional Hardware Upgrade

This kit is designed to install using factory hardware, but if you’re dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits separately to make installation even smoother.

Upgrade Today!

The Cruise Series 16-Piece Kit is the most complete suspension and steering upgrade for Jeep Wrangler JL owners looking to eliminate steering instability, prevent suspension failures, and build a fully adjustable lift kit tailored to their needs. With the ability to correct caster, eliminate wandering, reduce death wobble, and improve overall drivability, this kit transforms your Jeep’s handling, making it more predictable, stable, and capable on any terrain. Upgrade today and experience flawless alignment, precise steering, and enhanced suspension control—all in a kit that outperforms anything else on the market!

Notes: Some, (not all) factory axle mounts need to be "clearanced" to accept our larger bar. If needed, it is only a minor amount of trimming to be done. This applies to the front track bar only. Please see our Youtube channel for a video addressing this.

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you’re running a non-standard setup, call us before ordering and we’ll confirm compatibility.

Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.

Yes, if you’ve done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you’d rather have it done.

Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.

Teraflex’s lifetime warranty voids if you miss a maintenance interval. MetalCloak’s actual parts warranty is 12 months — their “lifetime” language refers to their service program. No conditions here.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

I wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

CORE 4X4 Company produces/manufactures exceptional products. My rear upper and lower control arms and rear track bar were powder coated custom Fox “Shock Orange” for my 2024 Bronco Wildtrak. OEM looks minimal compared to the CORE 4X4 control arms. Plus they’re adjustable, serviceable and rebuildable. Shipment was very fast and packaging used custom foam wrapped around the arms and heavy duty boxes. Not even UPS could damage. Korby L. was great to work with and responded quickly with emails and product information. Great products. Great people from the State of Utah. All Made in the USA. 5 Stars!!!

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!

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 :) .
