What should i be shifting at with 4.10's. I bought the car with the gears already installed and i expected some whine from the stock ten bolt. Once the new clutch goes in i'm actually expecting the rear end to go, but the point of this thread is to ask about how can i be sure i have 4.10 gears? Any way to know for sure, as in what speed in what gear are 4.10s supposed to be spinning?

 

Punch in your information HERE and it will calculate out MPH to RPM. BTW, you will need your tire size also.

 

exactly what i was looking for thank you
