I have an 01 that I'm trying to put a 3" lift on on a budget. I already have some 4" Teraflex TJ coils I plan on trying on the front but need some rear leaf springs, shocks and small parts to complete the lift. I looked at the RE 3.5" superflex but that's really more than I can spend right now. I'm looking at Rusty's and BDS for the rear leaf springs and maybe shocks and small parts kits. Who has better springs in terms of durability and ride/flex?
