Gearing ratios in the transmission and rear ends make a difference too.
Yep. The overall ratio is more important than just the diff ratio. Some people get hung up on the diff ratio, but it doesn't mean much unless you factor the tranny and transfer case into the equation.
For sure. With double OD’s on the newer automatics you can run higher numerical gear sets in the rear end to assist with getting a load rolling and then enjoy lower RPMs out on the open road. Makes for a versatile combo.
Wasn’t too long ago you had to decide 3.55’s for Highway and lighter towing with decent mileage or 4.10’s for all out towing with screaming RPMs while cruising empty.
