Have 2013 Suburban LT 4x4 has max tow package no rear air ride. I have one of the adjustable eBay leveling kits for the front it's the billet spacers you add. can raise 1 inch , 1.5 inch or 2 inch. I am thinking of going 1.5" with the new 20" wheels I have with 305/50/20 Nitto terra . From what I have read on here it seems I will be ok with no rubbing? If I go 2" will the front be higher Cali lean?
