The 4.10 was available with the NV 5600 but the gearbox has now been changed to a Mercedes G56 which is available only with the 3.73 ratio. The final OD ratio is different than the NV. The NV was the HD option and the Mercedes G56 box was considered standard from what I have been able to figure out. Not 100% sure about that. You can't order an '05 anymore anyway. It will be an '06.
