Are you running 37 in. or larger tires on your JK Wrangler or Unlimited? If you answered yes, we feel the RockJock Currectlync Modular Extreme Tie Rod is a mandatory upgrade for those who get their Jeeps out in the rocks! Being pro-active, so you don't get stranded in the wilderness with bent or broken factory steering components is the smart thing to do for your family's safety. RockJock's completely bolt-on RockNut Billet Aluminum Modular Extreme Drag Link is packed with features - and it looks awesome! Drag link bar is 1 5/8 in. solid billet aluminum stock with CNC machined RockNut ends and RJ logos engraved into it's body. Rod ends are the massive 1 1/4 in. RH / LH thread forged steel rod ends with removable rod end cartridge that are a direct bolt-in to your stock vehicle, or may be flipped and used in reversed orientation. Our RockNut locking nut technology replaces jam nuts with a locking collet style arrangement that cannot pop loose like a traditional jam nut. Aluminum drag link bar is finished in clear anodize, RockNuts are black zinc plating and rod ends are powder coated semi-gloss black so the unit is ready for install right out of the box!

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.

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.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

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.
