Product Details
The massive tie rod ends thread into the tie rod end body so that they may 1) be replaced without replacing the whole rod end saving cost, 2) the same threaded in tie rod end is used at all 4 points so only one spare would have to be carried, and 3) they may be unscrewed from the rod end bodies and screwed in from the other side if a flipped tie rod was desired. The tie rod tube feature machined-in wrench flats and jam nuts for ease of adjustment. This unit is a direct replacement for the stock parts. No modifications or machining to any part of the vehicle are necessary! NOTES: Flipping the tie rod would require retapering the tie rod end holes from the top side of the knuckle.

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.

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

Excellent service, Prompt responses when needing technical assistance, Amazing looking parts that fit excellently. I would recommend them to anyone looking for suspension components. Also very well packaged when we received the shipment, which means no damage from shipping company!! We went with the Crawl Series double adjustable kit and it definitely looks killer on our build!!!

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!
