What gears do I need?

I put 38.5 Boggers on my 98 Explorer Sport 2wd and it sucks gas and is extremely underpowered. It has the 4.0L OHV motor and is the 5 speed auto. What gears should I get 4.88's or 5.13's. Thanks Pat

5.13's (or even lower), no question. Many of us that have 4.88's and 35's wish we had 5.13's

Thanks Jefe I was thinking the same thing but wanted somebody else to say it too.
