It's not clear what you are asking for. Are you looking to change ratio's? Brand? What's wrong with yours?

The short answer is depends.  C20 assumes it is a 2 wheel drive.  What size tires?  What do you typically tow with it?  What transmission do you have?  What engine do you have and how healthy is it?  4.10 doesn't like highway speeds, subtle changes won't do much but effect tow-ability.  If you are looking for gas mileage even the highest gear you can find may hurt you if your engine is tired or not running right...My $.02
