longer shockes with Deavers U402?

I'll like to order some Deavers U402 for my third Gen tomorrow but I have a couple of questions.
My taco is a double cab, am I correct to assume the springs will give me 1 1/2 inches of lift?
I'm shooting for 2 1/2 front and 1 1/2 rear , that should keep it level, right?
And with regards to the shocks (2.5 kings with/Res) should the be 1 inch longer ?
Thanks for your help

 

That's not good. What are my options then? I'll like something flexible to take advantage of the limited travel.
My plan is Ext. king,TC UCA's up front with Kings also in the back but don't know what my options for springs are or should I just call Alcan and have them build me a set? .
Just want to keep it mild and simple 285/75/16 , just enough to take the family camping and occasional off road trip, don't want to spend all my free time working on a truck, done that already

 

Call Alcon.. they can make you a custom pack but will be almost double that of most others

 

You want the deaver j66 pack

 

Thank you!
