This all-in-one 7-piece suspension upgrade is built to significantly outperform factory components, ensuring smoother highway driving, superior off-road control, and long-term durability.

For a fully optimized suspension and steering setup, we recommend pairing this kit with the Cruise Series Rear Upper Adjustable A-Arm (CRS-J-WJ-AA1) to complete the rear suspension system.

  • Precise adjustability – Control arms adjust for lifts from 0 to 6 inches, ensuring proper axle alignment, pinion correction, and caster restoration.
  • Enhanced stability – The adjustable front track bar eliminates death wobble, wandering, and bump steer, keeping your front axle centered and secure. Adjustable from 2-6" of lift.
  • Heavy-duty construction – Built from high-strength steel tubing, ensuring superior durability for both on-road and off-road performance.
  • Advanced polyurethane bushings – Provides better responsiveness, reduced road noise, and improved suspension flex compared to rubber bushings.

Recommended Pairing

For a complete rear-end solution, pair this kit with the Cruise Series Rear Upper Adjustable A-Arm (CRS-J-WJ-AA1) to achieve full control over pinion angle and rear axle positioning.

Total Control Over Your Suspension and Steering

This kit is designed to eliminate common suspension issues like death wobble, axle misalignment, and instability at highway speeds.

When paired with the Rear Upper A-Arm (CRS-J-WJ-AA1), this kit delivers unmatched suspension precision and long-term reliability.

Durable Two-Stage Powder Coating

All components undergo a two-stage powder coating process for maximum durability and corrosion resistance. A zinc primer base coat provides exceptional rust protection, while the durable topcoat, available in 10 colors, offers a long-lasting finish and customization options to match your build.

Made in the USA

Proudly manufactured in Orem, UT, this kit is built with locally sourced materials to ensure high-quality craftsmanship, superior performance, and long-term reliability.

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.

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with Core 4X4!

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !
