RockJock's completely bolt-on Currectlync Steering System eases some of the pain of installing a JK front axle in your TJ, LJ, XJ, MJ or ZJ! The axle swap can be tricky, but it’s doable. But, what do you do for steering? Here is your solution! Features include an alloy steel 42mm, 1.65 in.) diameter tie rod, 1.3 in. diameter solid forged steel drag link, larger forged, greasable tie rod ends, premium jam nuts and adjuster and it's painted black, so it's ready for install right out of the box! Additionally, you’ll need a modified pitman arm to hook this all up. This kit includes a brand new TJ style pitman arm with the proper taper for the new steering system. Both the tie rod and drag link feature double adjusters so that they do not require removal from the vehicle for adjustment once installed. This unit is designed for use on stock height or lifted vehicles, but for those with big tires, these components are also compatible with ram assist steering. Components are completely bolt-on and kit includes our U-bolt style steering stabilizer shock mounting bracket to allow you to remount a steering stabilizer shock to the new tie rod tube.

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

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.

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

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.
