I went there twice and I won't go back. They do great work from what I've seen/heard, but one of the times I went in I asked about a budget boost (should be $100-250 plus labor) and they kept insisting that I go with a 4 1/2" lift (Trailmaster, I believe) for about $1300 (incl. labor). For the 4 1/2" lift, I guess that's not really a bad price, except that I told the guy more than once that I was only interested in a lift under 3 inches. I left feeling as though I was being made fun of because of some of his comments about small lifts being wimpy.
Then again, 4WDD must be doing something right because they're the only offroad shop within at least 35 miles and they've been around for a while. There's another one in Carlton, MI, I think, on Telegraph that I stopped in about two years ago. It was pretty clear I wasn't even going to get anything, yet they were really cool, answering questions and talking with me.
