If the info matters to anyone, I just put the steel leveling spacer kit from Tuff Country under the front end of my '02 4X4. It brought the front end up an exact 2". The truck now sits almost perfectly level, still a little lower in the front than the back, but not in a bad way (maybe only 1/2"). It needed an alignment following the install to fix the death shake I was now getting on cement bridges at freeway speeds, as well as the humming associated with a bad allignment toe. So far, I'm quite pleased with it. Does anyone know how big of a tire I could go now, keeping the stock wheels? I'm considering a 35" or metric equivalent, but I think that may be too big, any one know?
