How low can be done with just shackles on leaf springs

There are kits on EBAY that will sell the new hangers & shackles for a 4 inch drop. But that too may be customized by drilling holes to gain a 1" hanger-2" shackle for a 3" net. Grade 8 bolts should be used on those hangers regardless.

I am pretty sure your math is wrong. Moving on one end of the spring nets half of the drop. A 1" hanger and 2" shackle would net a 1.5" drop.
