RockJock's Adjustable Sway Bar End Link Set for the front of Jeep JL Wranglers and JT Gladiators features 8 1/2 in. long link rods with 2 5/8 in. of 1/2 in.-20 LH thread and 2 5/8 in. of 1/2 in.-20 RH thread, providing adjustment as-is and extra thread, allowing you to cut them shorter as deemed necessary by your application. Link sets are included in our Antirock Sway Bar Kits, but are able to be used universally in many applications to replace non-adjustable sway bar links. Additionally, if you have changed the lift amount on your vehicle you may need a different length of sway bar links to accommodate your new lift. You can simply buy a complete new link set to accommodate your needs. To accommodate the JL and JT application, this kit includes 3 high-end sealed rod ends that feature 12mm-1.75 RH thread studs and locking nuts and one thru-bolt heim joint, high-misalignment spacers and hardware for use at the passenger’s side of axle housing location. Jam nuts are included. These links and sealed rod ends are a direct replacement for link sets that feature heim joints.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

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!

Purchased a set of Trailing arms for my Ram 1500, quality is first class. I bought the ones with the Jonny Joints for more articulation and it appears from the construction I should get a lifetime of use, Zerk fittings are an added plus. Would defiantly recommend, and the the service team answered all of my questions.

Core 4x4 excels with precision and service and keeps nothing else higher in mind. Everyone I've met at the company is very honest and down to earth, 10/10 would recommend.

Bought a new 2019 Ram 1500. Had bad rear wheel hop since new, got all four core 4x4 control arms and it fixed the issue. Thanks

I wanted to take a moment and give these guys a shout out, I’ve currently got, for my xj, their adjustable control arms, tier 4 adjustable track bar and adjustable leaf spring shackles. You can always count on a fair price, high quality products, and quick delivery. Keep up the great work guys, will definitely continue to shop with you

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps.
I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well.
This was all done solely over email/descriptions/pictures/measurements.
Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.
