7.5 is an option...and trust me once you go just a bit higher, you will want MORE!!!! lol. Right now I am upset that I didn't go bigger right off the bat (save the money and then go bigger) but I had too do something other than stock, so I whent with the Fabtech 3.5 inch...and I do love it! It has put up with a lot of abuse. Its a start for lifting, and its a good lift. If you have the money though go with the 7.5
