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!

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 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!

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!!!

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 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.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.

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!
