You probably would want to just keep the brackets around until you do the lift. It's a TON of work to not do everything at once. And if you ever had the intention of putting in a front locker, or re-gearing etc. It'd be a good time to do that too.
I plan on ordering a set, not sure when I'll get around to it though, probably next year . I'd love to install a front ARB at the same time, but I think it's above my mechanical expertise. Any one want to help with that part
