I bought this setup after having years of steering problems on my lifted cherokee. The stock drag link struck my sway bar mount, so I had to flip the tie rod to the other side. This allowed the left wheel to rotate about 20 degrees independently from the right. This kit connects the wheels directly, and moves the union closer to the TRE, compensating for increased angles from lifts. After installing, the only play in my steering now comes from the box.
The quality is excellent, rods come unpainted, the instructions on their website are excellent, installation was a breeze after the drilling and reaming. Definitely a worthwhile upgrade! Feel free to PM me before starting this project for advice.
I would definitely recommend removing the knuckles and pitman arm, and drilling/reaming with a drill press.
