Product Details
| Brand | RockJock |
Overlanders and Racers! If you’ve been in need of a heavier rear sway bar to support the added load, and resulting sway) of the addition of a rack, a roof top tent, camping gear, etc. – or – if you are a desert racer needing more control, RockJock has the solution! Their 50 in. wide x 1 1/8 in. O.D. x 28 spline sway bar is a direct replacement for 50 in. wide bars in any of our standard Antirock Sway Bar kits – regardless of application. Because of the larger diameter and spline count of the bar, the sway bar arms must also be replaced with 28 spline arms as well as the sway bar bushings being replaced with larger I.D. bushings. However, with all of the upgrade parts in hand, you simply unbolt the arms from your existing bar, slide the bar out, replace your sway bar bushings, and then install this larger bar and 28 spline sway bar arms! Sway control will be dramatically improved in loaded or racing applications. Bar is constructed of forged 4130 chromoly and finish is semi-gloss black powder coat.

Got the CAMP version of adjustable control arms and track bars for our 03 TJ with a 3” lift and 33x10.5 KO 2’s.
Super beefy bars, great fit and adjustability.
Friendly advice and support from Korby at CORE 4X4. Good follow up as well.
The ride quality is great as well as the handling. I think it all looks pretty good as well.

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.

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 have recently come to know Core 4x4 when I purchased a Jeep XJ and was looking for a place that had dedicated XJ suspension and components. Here is what makes them different than most other shops. All of their components are top shelf quality and they back it up if you break any of it. I was able to see their shop when I picked up an order locally and was impressed with their attention to detail and how they assemble and powder coat each part. I had an issue with a shackle and needed the threaded shaft to be shorter. I called in and talked to Kaden and he told me to come by and they would shorten it for me. When I got there, Kaden and Spencer (the owner) met me and talked about options and proceeded to make the right adjustments to fit my XJ. Told me if anything changes in the future and I need additional length, they would take care of me. So what really sets them apart from others is their Customer Service. Try calling in to any other Jeep suspension or part shop and see how they treat you. Been there - done that.
Will continue to do business with Core and their team. Getting that kind of service for just a shackle has me thinking I may need to replace my JT components with Core's. Thanks Guys for being helpful good humans!

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.

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!
