'93 yukon front differential question!

['93Yuke]

how would that effect my gas mileage though?

It would probably improve it. You are losing some of it now with tires that big on stock gears. You acceleration must suck.

my acceleration is actually pretty good. It will take off and beat someone off the line at a redlight.. done it a few times. as far as i know it has the stock gears.. but it may have aftermarket gears. the speedometer reads about 10 mph slower than i'm actually going, but i know thats also due to the tire size.

tire size most likely. if it was gear was changed the speedo would read higher than actual speed if not corrected.

thats what i was thinking.
