A-833 2.47 1st gear change to 3.09

It's all in the combo of parts and it depends on what you're comfortable with, I put 8 3/4 in my vehicles and have different ratios of 3rd members to choose from, you would love 3.91's, just let the RPM's sing most of the time and when you want to go on a long trip 2.94's, it only takes 60 minutes to swap 3rd members.
