06 gt gears
 

Has anyone ran 373s with 18 inch tires with the automatic. How did it change fuel mileage. Drivability. Interstate cruising etc or would it be better with the 410s. This will also have the sniper tuner thx in advance

I would put 4.10s in it. I don't know about the 3V motors, but from talking to other mod motor owners it doesn't affect gas mileage much at all. Driveability should be improved, as it should accellerate easier around town with the lower gears.

I don't see 3.73's affecting the mpg either. That's what I plan to put in my 08

what gear does it have now?

327 gears and the 60 ft sucks

2 tons= 4.10s

My '08 has the 3.55s and I am wanting to put in some 4.10s. Are there any shops that are capable to doing gears in the Jacksonville/Anniston area?

several people do jobs on the side they will chime in im sure!

I would do it for you but my schedule is pretty tight until the end of the year

check with Jacksonville Muffler, talk to Marc. Otherwise, wait for qwksnke to get freed up...I know he has done 100 plus gear swaps, two on my cars. both of them do top notch work. :nice:
