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.

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 ! ! !

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.

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last.
I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days.
If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

I have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that.
Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

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!!!

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4
