Look on the sticker on your driver side door. There is a code for your axle, google it and it will tell you what you have. If you have 3.55 (which you likely do with your setup) it is your best bet. If you're towing your boat no problem, going with a 3.73 is useless and will harm your MPG, going with 3.31 will give you better economy but you will lose torque. 3.55 is the sweet spot in the middle with enough power for towing moderate loads and for Mpg's. I'd keep what you have if you want economy.
