I run a level lift on my 2011 Tundra Crewmax. It allows me to run 35's up from the stock 33's. I have 4 inches of total lift when done. I measured the tops of the wheel wells before and after. It's a nice edition. Gave the the little extra ground clearance I wanted.
Leveling kits are ok if you're not beating your truck up off road. If you spend any amount of time in rough country I would seriously consider dropping the coin on an Old Man Emu kit or some coilovers like Icon or Toltec. The ride will amaze you and if won't stress your front end at all
