This is a blazer belonging to a member of theTrail Krawlers websight. It is a very long thread, but he really goes into detail about what is involved in doing a huge lift, heavy axles, etc. I'm lucky that I live about 30 miles from some really kick-butt trails, and look forward to spring coming! This is about a 2hour read, so enjoy.
