I don't have it yet, but I'm going to get it. I really think its the solution, and all the GM truck guys I know locally are gonna be getting it.
I think its about 650bux Canadian. If you combine this kit with the new ISS shaft and Bearing, and some MOOD HD tire-rod ends/pit-man/idler, and the Cognito or Supersteer Idler w/brace, you should have super beefy tight steering that will last near the life of the truck, at-least that's what I think/am going to do.
Kinda sucks we have to spend that much to make it right, but the stock stuff is JUNK, and the direct replacement stuff is JUNK, so its either Patch it or Fix it. I personally don't mind spending money improving steering.
