So, I'm not exactly a hardcore wheeler. I use 4x4 on average twice a month unless it's hunting season, then it's more! I'm not going to run any XTREME trails or rocks, just the occasional mud bog and washed out fire roads/trails. My truck has full 3/4 ton running gear and it's my baby. I plan on fixing it up. It's not hardcore, I run a 700R4 and a 208, they have both been rebuilt and the 700R4 is as beefy as it gets. I am putting '35s on for now, but eventually it may get a little more lift and 37.5s I don't plan on ever going any bigger with this truck because I'm building a Dodge M880 w/ a buddy that will get a D60 front and all the good stuff. And if I ever do build a real trail rig, it probably won't be my blazer but a Dodge or a fullsize jeep. Don't get me wrong, I love my Chevy and it's easy to live with every day, but if I ever get real into this thing we call 4 wheeling, it will be something besides my blazer getting built. I'm thinking that a true trac front diff and 4.88s or 5.13s will eventually get dropped in, aftermarket axles as well. I just want to make sure I'm not wasting me time before so though, cause to tell the truth, I'm always on the look out for a D60 front anyway... Just to have sitting in the back yard!
