Congrats. Very few had 4.10's from the factory, or at least not as many as had 3.27's and 3.73's. Some had such low gearing since it was still very much a truck, and lower gears helps with towing and gives a better crawl ratio for off-road. The tow package isn't gear related, even models with higher gears had the "tow package" which sometimes was nothing more than "super engine cooling"..either a heavy duty radiator, fan blade with more blades, or something else.

Where/how did you find out your '91 had factory 4.10 gears?

What's the code on the driver's door jamb, under "axle code"?
