Eric Hansen of yota masters uses the 3" lift buggy allpro springs, He swears by them. He has shown me a the difference between the regular 5" vs. the buggy lift. I myself have the allpro 5" and they work great. Good street ride and flexy offroad. Next time I will go marlin's because of the quality. From what I've seen, Marlin's spring packs are nice and straight unlike my allpro, they are uneven. I wanted to sport a taller truck for coolnest factor. If you search around you'll see eric's truck with alot of great flex.
