I'm on my laptop now and I feel fairly confident saying that it is a Zone lift. I could certainly be wrong though.

Eye_4_an_Eye, to my knowledge, only Pro Comp and Fabtech make lifts for us and both are 6 inch kits.

 

I always wanted a lifted HD like this one. bitchin truck!

 

hows the Fabtech? I've heard a lot of bad reviews for the Pro Comp

 

Really? Both should be solid, but my choice would be the Fabtech and I've never heard anything bad about it. I think most would agree that the Fabtech is the better kit of the two as well. I'll likely end up with the Fabtech myself, at some point . . . It looks much better (the front crossmember/subframe does) too. "Pro Comp" just has a negative connotation with me, but it probably isn't justified.
