I might be interested but I am trying to figure out how you are getting 5".
Maybe I am thinking wrong but on my Suburban my bottom of axle to spring is 3.5" my spring pack is 2 5/8" looking at the pictures it looks like your bracket is 3/8" thick and there is a gap between the bottom of the axle tube and the bracket of at least a 1/4".
I get 6.75" +/- of drop
