The formula is probably asking for outside tire diameter which would be more like 26" plus depending on the tire you are running. Might want to recheck. I don't think you want a rearend with less than 3.43 gears with the OD transmission. The lower the gear ratio number the higher the rearend gears which equals less torque. | | |
