I am talking about a 2 speed rear end... like a 3:73 and a 4:30.
they are NOT the same thing.
But the net effect is the same. That's why OTR trucks have transmissions with 9 to 18 speeds and typically have single speed rear axles. Modern six speed transmissions have made split rear ends unnecessary, especially with the abundance of power available.
