Thread: what is my differential ratio, and first gear ratio?

oh... ok, i think hey have options on the lsd's for higher ratios... you would need to tune the car to make this work with the speedometer and everything right?

I seriously doubt they have options for different ratios, as the previous posters said, ALL HD diff are 3.29:1. The gearing changes come through changing the sprockets on the chain on the input side of the trans. Now, they may offer to have different VSS reluctor wheels installed on the diff for different gear ratios, but those don't change the gear ratio itself, they are just for tricking the computer after you have changed the sprockets.
