heck yeah now your talking. Go with the 60/14b and go 42's. You need to in order to get the same ground clearance that 37's will give you on a toyota axle.
Trust me you won't be dissapointed if you go that big. I sure don't miss the toyota axles when I'm in the rocks. I just blew a toyota hub on my tacoma this weekend in the snow. Wouldn't have happened if I had 1 tons.
