If you go ARB be careful of your air lines. In the last year I've seen several of my buddies blow an air line and lose their locker for the rest of the day. I'm pretty sure a few of them went ahead and upgraded to steel braided air lines.
Nah, it was a hot day, air lines touched something hot and just exploded. The lines were plenty long, and didn't just get ripped out. Even if they had been ripped out, thats another argument against an ARBi've heard that about plastic lines but my rear locker plastic line has rubbed through the undercoating and the paint on my gas tank skid plate. nothing but bare shiny metal. the best part is i can't even tell on the line where it rubbing.
could it be that there lines were ripped out from being over extended?
