I have an 88' supercab ranger 2.9, fm146 tranny, 3" body lift, 31' tires, and3.73 gears with a limited slip 7.5. it does'nt have any power at all going up the hills here in WV on the highway id like it to have alittle bit of passing power. I was wondering if 4.10 or 4.56 gears would be better and how much it would hurt my mpg. its getting 12mpg right now i dont think it can get any worse. ill take all the help i can get thanks.
