    Stock gear ratio is 2.85, ofna 6&8 spyder,Losi LST2,UE diff ratio 3.31.

    The higher the number the lower the ratio, so you will have to make it up by changing the spur/CB ratio.

    40/17 with stock 2.85 gears, when you change to a 3.31 gear these spur C/B will be the same,
    40/20
    38/18
    36/18

    You can play with the roll out calculator here, just put in the correct info.
