Lift on 2019 Tundra Crewmax

I am getting ready to buy a new limited Tundra Crewmax and want to lift it just a little like a leveling kit 3" in front and 1" in back. I was reading about Ready Lift's product is only like $359. How much would I expect to pay for labor on a lift like this and I also want to add some taller tires (Nitto Terra grapplers) with "stock trd wheels" to fill up the wheel wells. Anyone have any pic's or prices I will pay?

Do I need to get new Bilstiens?

 

There are many threads on Tundras about different ways to do this. I've spent many hours over the last couple of months reading about various ways and here is what I've come up with for my plan.
Right now is probably the best time to buy any suspension product (aside from Group buys which are sporadic). Being that I'm not ready to sink 2k+ into a suspension being that my current factory one is still fine and I don't do any serious off roading, I will most likely get a 3/2 ready lift in the next 24hrs. This is to accommodate 275/65r20 Nitto Ridge Grapplers and keep some rake. If/when in the future my suspension needs replaced, I'll be more willing to pony up the 3-5k for a good (not excellent) system.
If money wasn't an object, I wouldn't do the Ready Lift. So, if I were buying a brand new 1794, I'd also be factoring in the suspension system I want (Icon stage 3 or 4 or Kings). I have no experience with any of the above, just hours of reading and researching, but you'll want to do your own and read from people who have had the experience.
I've found the Tundras forum to be a great source of information and most everyone is willing to help each other out and at least get you pointed in a direction.
