to hold ,e off till crossover and marlin springs i got 4"procomp springs for the front for $50 a piece from 4wheel parts.
then i did a chevy spring conversion, and i can run 33"s with no rubbing. i want to go 36" irocks later but this will hold me off. they are kind of stiff, but they compress ok while flexing. but they were cheap and they fit, all i needed were bushings and a drop drag link.
im not saying this is the ultimate set up, but it was cheap and it works.
i have no problem with running 33"s with stock gears, but i have a 22re with maybe 16 more hp
