If you want to keep the leaf springs, the cheapest add on that actually works pretty good is a set of Lakewood style slapper bars.....bolt 'em onto the lower side of the spring perches and make sure that the snubber is all the way tight up against the front spring eye (no gap between the rubber snubber and the spring)
At a later date, you "may" want to consider stepping up to a ladderbar. This CAN also be used with the leaf springs, but a housing floater would need to be installed as well, to keep the bars and springs from binding up.....
Good Luck!
