RockJock's completely bolt-on Currectlync Steering System for JL Wrangler, JL Unlimited and JT Gladiator vehicles includes their 42mm, 1.65 in.) diameter chromoly tie rod and organically shaped, forged chromoly, maximum articulation drag link. Additional features include larger, greasable forged steel tie rod ends, premium jam nuts and adjuster and it's painted black, so it's ready for install right out of the box! Kit also includes RockJock's JL/JT High-Mount Steering Stabilizer Relocation Bracket Kit for the passenger's side of the factory stabilizer shock, which moves the shock from the tie rod to the axle housing, as well as way up out of harm's way. A heavy duty stabilizer shock mounting kit for the opposite end of the factory stabilizer shock is also included that moves that shock mounting location from the axle housing to the tie rod tube. 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. This easy to install kit requires no modifications or machining to any part of the vehicle!

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

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.
