I went with Teraflex level lift (1" pucks). With my bumper (RR XHD w/ stinger) and winch (Superwinch 8500lb, forgot model #) I still have a little rake but less than I did from the factory w/o any mods. As far as suspension travel goes: I'm running 35's with a 2.5" Procomp coil/shock lift... after the pucks I can still rub my fender bracket (the stock fenders are cut) at the limit of my uptravel and my downtravel is limited by my shock at the same point it would stop with or without a puck, so with my particular setup I don't think the puck affects suspension travel.
Oh and by the way Teraflex is here and offers us a discount.
