Sell a child for a winch bumper - They are about 700 from arb.
Yeah longer springs. Devon4x4 might be able to help? OME ones. Yeah just wind up the tortion bars, don't go over 2" though. Your stock shocks are fine at 2", but an upgrade is never a bad thing. Just keep away from milners, you'll get a 2" lift alright, but you'll have a 2" sag in 12 months.
