Anyone swap the high 3.42 to a lower 3.73 or more on there 2012 Crew Cabs or similar. I am not sure why GM chose this gear ratio on there newer trucks. I have the z71 and was stuck with this option with no other choices, not real happy about that. Especially with the 6 speed you would think you could get a lower gear. I am going for it but wanted to hear some experiences if anyone had done this? I have done it on the older trucks with great results, but that was going even lower with the 3.90 and 4.11.
