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.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do!
Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me.
As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a
Difference from the cheap oem rear control arms to these and the pan hard bar.
Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop!
Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.

Amazing service. Bought a track bar through Americantrucks.com and they sent it with the wrong size bushing sleeve. Korby at Core 4x4 was quick to get me the correct size and very responsive. Will definitely be using more of their stuff.

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!!!!

I don’t write reviews often, but Core 4x4 absolutely earned this one.
I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts.
That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed.
The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots.
Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right.
If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

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 :) .
