i run 39.5 iroks with allied 32 bolt beadlocks on my efi 85 reg cab pickup, 30 spline bobby longs with hub hears, hydro assist, 5.29's, marlin high steer arms and currently stock knuckle studs(i have arps', just havn't had the time to put them in yet). I love the 39.5's, almost makes most trails too easy though. DO IT!
