I went 4.56 my shop was able to put a GM gear American axle in my front and a nitro in the rear. The front they had to use a different carrier I don't know the technical term. A 9.25 in the front.

Rear diff only is 11.5". Referred to as a "Dana 80". It's made by American Axle tho, so it's not a Dana technically. Please report back on your RPMs vs MPH in 5th and 6th gears when you can. I don't feel like doing math this early. Lol. Thanks. I am considering 5.13s if they'll fit. I have same damn truck as you with 4.10s now.
