This heavy duty and light weight truss system is designed to take serious abuse and reinforce your front High Pinion 30 XJ axle. The 1/4 inch thick truss top and 10 ga. gusseting incorporates a unique design to strengthen both axle tubes, not just the long tube. The precision cut and formed components of this setup ensure a hassle-free installation. Not only is this just a truss, but you also get a Complete Polyurethane Bushing Replacement For your upper control arms, or you can even upgrade to Currie Johnny Joints.
Features include:
- Sold as Each
- Upper Control Arm Options: Currie Johnny Joints
- 1/4 inch and 10 gauge (.130 inch) mild steel.
- Precision CNC cut and bent for great fitment.
- Truss is low profile to allow clearance above the axle.
- Truss spans length of long side and short side.
- Truss is reinforced using interlocked 10 gauge thick gussets for maximum strength and easy assembly.
- Overall low profile design means your axle is stronger, sleeker, easier to fit into any vehicle, and less likely to interfere with vehicle components.
- This Kit requires general welding and fabrication skills including welding to the cast center section. Welding should only be done by a competent welder.
- Artec Industries implies no guarantees or warranties and is not liable for improper installation.
- Some grinding and fitment may be required when installing this Kit. Every axle varies slightly and some fabrication may be required.
- In rare and extreme cases, the truss may come into contact with oil pan.
- Prior to operating the vehicle, remove the coil springs, cycle the suspension including full compression of both sides simultaneously and add bump stop extensions to prevent damage to oil pan.
Truss ONLY - No bushings/joints/keyed tabs included. Key hole slots on top of truss where keyed tabs would go must be filled with weld. Use this only if you aren't connecting the passenger side UCA or are reusing the factory bracket (see 4th image for details). Daystar Bushings - Includes bushing, inner sleeve, and thrust washer for Driver side and bushing, weldable outer sleeve, inner sleeve, and two keyed tabs for Passenger side. RockJock Johnny Joints - Includes 2.0" Press-in machined Johnny Joint (CE-9112M), 2.0" weldable Johnny Joint (CE-9112), and two keyed tabs for Passenger side. Both joints include greaseable 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.

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 :) .

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.

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!

In September 2025, we visited CORE 4x4 in Orem, Utah. CORE 4x4 makes control arms and other similar parts that stiffen the suspension of an off-road 4x4 vehicles, so that the off-road vehicles can travel on more rugged terrain. CORE 4x4 used to share this building with another business, and since this other business has moved elsewhere, CORE 4x4 will continue to expand and grow their business. Good for CORE 4x4 to be a growing company and to expand into the vacant part of the building.
