Key Features and Benefits

  • Heavy-duty DOM tubing construction – Lower control arms built from 1.75” OD DOM tubing, upper control arms from 1.5” OD DOM tubing, all with 5/16” wall thickness for maximum strength and durability.
  • Precision steering system – 2.5-ton aluminum steering kit enhances responsiveness, reduces play, and improves handling in both on-road and off-road conditions.
  • Optimized suspension geometry – Fully adjustable control arms allow pinion angle corrections, caster adjustments, and axle re-centering, designed for lifts from 0 to 6 inches.

Heavy-Duty Adjustable Track Bars

Front and rear track bars work in tandem to keep axles centered, reducing bump steer and body roll while improving overall drivability and ride quality.

For maximum suspension and handling performance, pair this kit with the Camp Series Front Sway Bar End Links (CMP-J-JL-FEL2) and Rear Sway Bar End Links (CMP-J-JL-REL2).

Whether tackling rocky terrain, high-speed desert runs, or daily commutes, this kit prevents wandering, reduces bump steer, and enhances steering feel, making it an essential upgrade for lifted Jeeps.

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.

Optional Hardware Upgrade

Designed for easy installation using factory hardware, with optional Grade 8 hardware kits available separately for rusted or worn-out bolts.

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.

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.

Ordered a control arm and track bar kit for my WJ from Core 4x4 on Monday 7/28 and received it today, Friday 8/1. Im not a state or two away, im in CT aka the other side of the country. Communication is phenominal, emails were responded too in an hour or less. Parts arrived well packed, not damaged, and are great quality for my needs. There arent many companies left that service customers as well as Core 4x4 and i wont hesitate to check them out again if i need something else. Well done!

Excellent, strong, and durable products—perfect for both on-road and off-road applications. The customer service is outstanding—friendly, knowledgeable, and extremely helpful with understanding installation and ensuring I got exactly what I needed. I would definitely order again. Top-notch company with high-quality products made right here in the U.S.A.

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

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.
