w0wza!!! after some reading!!! def going to go with the 52" springs and shackle flip!!!
just keep in mind if your going to be seeing a fair amount of street time that long leafs can be a little, unrulely... 52's up front also REQUIRE x-over steering.. great mod for these trucks no matter what leaf setup...
a flip out back is always a great choice unless doing heavy towing... put 56"s in with that flip and you'll get some more flex too.. thats my rear setup, but i'll run standard length front for a little more street friendlyness...
frame braces at the steering box are always a good thing too...
