Gears & Axles - 3.73 gears ?
04-10-2012, 08:15 PM
Ok I am new to the forum I recently bought a 02 ws6 fro a friend. Well the rear end makes an awful lot of noise and I'm getting it all rebuilt. My question is should I go to 3.73 gears? I have the 4l60e and only have a slp exhaust with highflow cats and a lid. The gears are only 200. So i just wanted to see your guys opinions. I figured they should give me a little more power out of the hole. So please help me out I'm getting it done Thursday..

Ok so another question I had was, what about getting the car recalibrated? Is it going to mess my shift points up and when the car will downshift at wide open throttle? Right now at a 25 roll it takes off amazing I really don't want to lose that. Will I just have to so a roll from 20 instead. Thanks guys

your speedo will be off...you have to tune it to correct this. You'll love the 3.73s

Ok and could I do that with any hand held? I found a jet programmer for 200 bucks. It's not just one of those chips it actually let's u tune different things. But thank you guys for the replies. Glad to have a trans am

373 is a good gear good on highway and mild performance

Not to jack the thread but since his question has been answered, what is everyones thoughts on gearing a stock 10 bolt? Assuming the way you drive it stays the same, will it reduce the life of it at all?

3.73 for sure....

What kind of RPM's are you guys turning on the highway with 3.73's?
04-18-2012, 08:07 PM
With 2.73s I was at 1900rpm at 70mph. With 3.73s I now run 1900rpm at 55mph. Not bad.... Increases exhaust volume, increases sotp...pulls harder throughout the rpm range.
Snappy off the line.
Lose 1 or 2 mpg depending on your car/tune.. but it's not really noticable comparably to the plus side of gears.
