Economy axle ratios in the range of 2.7 to 3.1 are poor for towing.
Performance ratios of 3.7 to 4.3 often are very good for towing without
a severe unloaded gas mileage penalty. There is a wide variety of axle
gear sets available from after market sellers. I bought a set for my '98
F-150 last year for $480 installed from a local hot rod shop. I changed
3.08 to 4.10, I compute that changed the trailer towing (5 speed manual)
capacity from 2200 pounds to 4700 pounds. It had virtually no effect on
gas mileage, and driving is a lot more fun because it has great throttle
response.
