I am from a farming, fix your own stuff background. My dad taught us to
use what we had before you buy. I raised the front of my week old Tacoma
yesterday with spacers made from heavy multi-ply belting, conveyer belting stuff. One 1/2" and one 1/8". I used the preload spring method and the results were nice, the truck came up a little over an inch. I cut out some extra's to fit on top in case I want to raise it more.
These spacers may not last as long as the $60 plus shipping ones, but hey
if they don't, I'll try something else.
Total time working alone was 5 hours and that included cutting out the spacers.
