Also, don't make the same mistake most people make by comparing the worst OEM gear option to the next step. Think about it this way... whats the best OEM gear option available in your platform? (in this case, 3.73). So now pretend you're not "handicapped" already and have 3.73s.... what gear ratio would you like to have?

I've seen this with multiple truck platforms. There's no reason to handicap yourself just because your OEM options set you up with the weakest gears from the factory. Pretend you have the "best" gears from the factory and work up from there.
