Thanks for the link. Yeah, I've seen that kit. It's pretty sweet, but there's no way I'm dropping that kind of coin on a leveling kit, haha. I understand what you're getting (upgrading) with that kit, but it wouldn't change the look of the truck enough to justify the cost for me. If I was going to spend over $1200, I'd go with a full 4-5" suspension kit and crank it down just enough to clear 35's.
I considered running something like the Rough County 3.5", Zone 3", or Tuff Country 3.5". Those kits come with new keys, new shocks (or shock extensions), differential spacers, and new UCA's...for well under $1000. In fact, the RC kit is only $550. If I went that route, I'd probably leave out the rear block and crank it down to 2-2.5". That would probably ride pretty good. I'll most likely just crank the factory keys 1.5-2" and be done. Maybe add longer shocks or shock extensions if necessary.
