As I'm looking at trrucks and towing capabilities, in some cases it varies with axle ratio. While I understand the basics of gearing I can't say that I have a sense of the difference in feel and drivability of say a 4.10 vs 3.73. It seems most trucks have the 3.73 gears, I assume because buyers were hoping for somewhat better mileage. Assuming a V10, questions:
These questions assume that the 5W would fall within the towing capabilities of a 3.73.
Thx
- How big of a difference in mileage would one typically see comparing the three gear ratios?
- How much difference in perceived pulling power would one see between 3.73 and 4.10 (seems to be the two most common)? Is a 3.73 truck going to be a slug?
- How much difference in descending hills? Noticeable loss in engine braking requiring 1st gear for example when it might not have been required? Still not enough in 1st when it might have been good with 4.10/4.30?
These questions assume that the 5W would fall within the towing capabilities of a 3.73.
