Level suspension

Hi Need some advice I have decided to use Bil 5100"s front and rear measured 35 inch front... 36 inch rear If i set the 5100 at the one inch slot it will be same as rear
if all as it says. Now if i want to raise it to 2 inch what will I need in rear to keep it level besides the 5100"s any advice appreciated The PDf service manual i found here is great Thks
2020 SR5 4X4

 

1" block in the rear works perfect with 5100's.

If you want a stiffer spring, an add-a-leaf will give you 1" as well.

 

I suggest add a leaf

 

You get more purpose from a aal haul a little more or better ride when loaded I have a aal in my tacoma does great haven't hit the bump stops . When I was stock with a my camping gear I would always hit the bump stops

 

This ^^^^^

 

Thanks for all the good responses, and 1 opinion
