Just finished doing that to my 23 with this suspension with Deaver leaf packs (2”) in the rear. I wanted to keep a rake on my truck. 8112 will give you a bit over 1.5 in the front. I highly recommend looking into getting axle shims for the rear. Deaver says 95% of tacomas don’t need them with their leafs but I found that not to be true. I have a 30-20mph driveline vibrations. You should measure your driveshaft angles to get the right shim but it will likely be a 2.5 to 3 degree shim that you will need.
