i've been looking for a good combination of springs for when i get new tires for my '79 yota. i've pretty much maxed out my capability with stock 28s(had 31s and no lift, blew a tire, hard to find around here[gateway buckshots]) and i want to go to something a little bigger. i'm figuring 33s will be a good match for my pickup. i'm thinking about running chevy 1/2 ton springs in the rear, and possibly moving my rear toyota springs up front and using boomerang shackles. would that be a decent flexy setup for the size of tires i want to run? can i borrow anybody's leaf pack recipe?
