Lift Kits - Rants and Raves

I've got a 98 2dr Tahoe that I want to lift, but I am not sure about which lift kit to put on. I am considering a 2 1/2 inch from Rancho or Superlift, but will most likely go with a 4" lift from Tuff Country or Superlift. I am not very well educated on what makes a good lift and what lift kits a particularly good on Chevy's with IFS. Any help? Also, if you know the maximum backspacing for the lift your talking about that would be great. I wanna go ahead and mount some 33" Bridgestone AT Revo's on some AR Diamond Back wheels with 4.5" backspacing, but I dont wanna end up deciding on a kit that requires a backspacing of less than 4.5". Any pictures you've got and want to share are welcome!

Thanks!!

Doesn't anybody have any suggestions as to the best lifts on the market for a Tahoe??? Or are they pretty much all the same?

Go with the Rancho... Stay away from the Tuff country, Rough country or Skyjacker...Procomp, RCD, Dick Cepek are also some good lifts.
