I thought my rig had good flex until I saw Micah's rig... my 6" superlift springs with dual shocks isn't gonna win any rock crawling competitions but she still holds her own. Now I'm hellbent on doing a 56" swap but theres the question of my old 6 inch lift blocks... Don't know how tall the actual blocks are but I'm guessing around 3 inches. Can I use my old lift blocks with the 56's? About how much lift would that be if I could? Will I need to relocate anything like shackles, etc?
