You went with the full 2.5" level option to make it even Lou? I ask because I have a 2015 Denali and am looking for this exact setup. I had been eyeing the 275/60R20 BFGs but if the 305s work on the stock rims I'll be looking at those.
I'm looking at ordering an Undercover Flex. Anyone who's recently ordered one online, how low of a price were you able to get from sites such as truckchamp and autoanything?
