I'm in the slow process of acquiring a 2 speed pig for my '57 2 ton and it should be a good addition, currently the rear is a single speed 7.20:1, the 2 speed will have a higher high and a lower low. I'm not expecting to ever take this truck on the interstate but it might do 55-60 against the governor.
What gear ratio 2-speed have you found for your '57 ?
