if its a cheap option and stuff needs fixed anyways, sure.. go 3.73's or even 4.10's. a lot of our ranger motors like higher rpms to an extent. i don't know anything about the 3.0 tho...
but usually the difference of just one set range is minimal.. usually won't even notice it a lot. i like my 3.73's for 30" tires, but i have a 4.0... so.... i have power. lol
