What do you think? Everyone i wheel with runs 4.56 and does really well. This includes trucks on 42's, 39.5's, and 37's. My blazer is going to be down for a lil while as the transmission gave out for the 3rd or 4th time since its rebuild in feb. So while its down im going to throw a 14ff in the rear so i can stop worrying about that 10b. I have a 350, TH350, NP203, and 38" TSL's. I still drive this on the road and gets me to where we wheel and back. I plan to go bigger tires far later in the blazers life, but right now 38's are perfect. What would be best for offroad but still do alright onroad also?
