Product Details
RockJock's Antirock sway bar kits are available in a universal fit configuration for those building their own custom rigs and rock buggies. This universal kit features a 36 in. torsion bar length and 17 in. long fabricated steel arms. Vertical links use a 14 in. long 1/2 in. x .20 RH/LH threaded rod that can be cut down to your desired length, and the necessary 1/2 in. x 20 thread heim joint rod ends, jam nuts, and tabs to weld to your axle tube are supplied. Also supplied is the universal weld-in 1.75 in. x .095 wall DOM tube that is cut to the proper length to work with the torsion bar length, and the delrin bushings to support the bar in the tube. The 36 in. bar is a .750 in. diameter. These kits require fabricating for installation -- these are NOT bolt-on kits.

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 experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

Awesome product and service! I even got some of their swag because it looked pretty darn good. I will definitely be going back and would suggest this business to others looking for quality control arms. Buy local!

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!
