I have some 2in. skyjacker coils(132X) and 2in. blocks if interested,but you may need drop brackets for proper alignment,they lifted my truck too high without drop brackets to align
It is a really common way to do it.
Ford did it but with one big hunk of cast iron in the 2wd F-150's. Welded together decently the washers are not going anywhere.

You will never see it done on TV because it is a market washer companies haven't really started pushing yet. The regular lift kit companies pay the TV shows to promote their stuff a lot better.
