i didnt even have to read any of this thread before i was going to say "hell yeah, get some gears" 3.73's are great...i can tell you that cruising on the interstate at 70mph, the rpm's will be right around 3000 rpms...your rear tires wont like you for too long and i usually get around 250 mile per tank on a slightly rich tune...i would recommend that you wait to upgrade your gears until you have the new rearend you are looking for...that way you dont pay for 3.73's twice if you dont have to...just my $.02
