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.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

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.

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.

Great company, who worked with me on shipping parts, to arrive in time for a show, when I explained my concern of possibly not getting the control arms in time. Quality is amazing on the part, affordable price for what you get, and the powdercoat is top notch, not a single issue with this product, would buy again.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!

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 ! ! !
