You can't combine the leveling kit, and another lift. Max the stock suspension will do is about 4" but your ride will be in the crapper!
2.4" will level you truck. 3" with the 1" block will also level it. (With minor rake)
But if you add the Bilstein lift it will over stress your suspension.
And if you do a 3" lift you'll need UCA to get your truck to the "Ideal" alignment settings. (But not required)
