you mean you want higher gears... maybe to 3.73
now you could do that but its gonna take a while to come up with the diff its gonna cost to do it....
your looking at around 300-400 for gears depending if you need a master install kit or not and they usually charge 250-500 an axle to change gears....
so if you factor in the amount of money you will save by goign with 3.73 it will prob take you years to come up with your initial investment
