had it installed today at 4wheelparts, what it does is, when you lift yur truck yur drivelines are at a wierd angle, making a vibration at slow speeds and at highway speed, anyhow this corrects it, took bout 30 minutes and 75 bucks but the truck feels like its stock again. it's nice the power feels alott smoother too! anyone who lifts with an auto trans needs to do it!

info, pics, details! had the 6" with 37's and just went to a 10" and soon to be 40's. is it a re-indexing ring? or does it lower the whole shebang?

For that price and how long it took to install, it must have just been a new transmission mount that allows the transmission and transfer case to lean down a little. I don't like that idea because it is putting more strain on your motor mounts and the bolts that hold the transmission to the engine. An indexing ring is the way to go. The rear driveshafts are so long that you can have a huge lift and no vibrations back there. All you need to worry about is the front shaft, and the indexing ring fixes that without screwing with the transmission mount.
I'm going the "super cool" way and putting Dynatrac locking hubs on mine in a few days.

I got one with my 6" superlift kit, but it doesn't work for the manual tranny. I haven't had any vib issues anyway, so no loss really.

yea it is a piece that bolts to the crossmember, and lets the powertrain lean a bit, but not enough i would think to stress anything, driveline angles look just right now, everything feels nice and tight too
