Mossy you will be waaaay to high geared with either of those gear choices. With taller tires it will take MORE rpm to keep em turning that it does with shorter tires and stock gears. I wouldn't hesitate to go into the 5's and the 4:88 just might be too high..
Since you have a choice you should be VERY careful which you purchase. You will need to use high gear and with 4:56's it will be lost to you forever.
