Hey guys, I have searched on here with no luck so here I am asking 2 different questions. First, I've seen people mentioning keeping their leveling kit and installing a lift kit as well. Is that advisable? I bought my truck new a few months ago, 2011 crew LS 4x4 with a dealer installed leveling kit, 20x9 Ultra Barrons and Duratrac 305-55-20's. Now I just bought a 7.5 RC lift and I'd love to run 37's. Am I crazy to even think they might fit?
