Rear axle ratios and impact on towing
Suppose you have a choice between two axle ratios, say they are a 3.09 and a 3.45. And let's say the vehicle has an 8 speed transmission, so there's plenty of gear flexibility. Ok, so there's roughl...

The trans gears DO get closer together with a lower R&P! The top speed will be slower and you'll have the same number of gears so that makes the rpm change between gears closer. Mui bueno for towing! Craig
:R Oh boy!
If you have a 15% gear drop between 3rd and 4th with 2.73's you will have a 15% gear drop between 3rd and 4th with 4.56's.
The % stays the same!!!!!!!!!!!!!! Just because you have to make the gear change faster does not mean the % between gears or the ratio between the gears somehow magically changes.
This is almost as bad as people saying gears make more horsepower. :R
In the trans the spread between the gears is the same. At the wheels is where the difference is. Which is why the trans will shift faster with a lower gear ratio! Each gear is more efficient.
