3.73 or 4.10 for the rear


I am trying to decide if I should put 3.73 or 4.10 gears in my 98 gt it is a daily driver at this time but may not be soon so I don't want my rpm to high for the high way it is a five speed if anyone has these gears what is your rpm at 70

I would go with the 3.73 !! Thats what I have and they are a good gear !! I cant tell ya what the RPM is at 70 because I have my speedo unplugged but its not that high somewhere between 2000 and 2200 I think !! but the 3.73 is a better gear for the 5 speed I was told !
