Good info so far in this thread.
As someone who is running nearly the exact same setup as you, my advice to you would be "don't do it." Hold out for a far superior 2.5" setup (2.5" refers to the shock body diameter, not the lift granted by the setup) from King or Icon and never look back. I have the Tundra/LC, and after driving a truck with a full 2.5" setup, I no longer enjoy driving my truck nearly as much. It's harsh, jarring off road, and leaves much to be desired on-road as well.
You can get a full King setup for ~$1,800, and it's worth every penny imo. So in short, don't do your proposed lift, don't sell yourself short. I wish every day I had just saved up a little longer and done it right.
