4:70 or 5:29

are you talking axle gears or tcase gears?

i am assuming axle, i dont htink there is a 4.7 gearset for the axles... there is one for a gear driven tcase though

gears for your 33" tires should either be 4.88 or 5.29

5.29s might be a little bit on the low side, but if you ever plan on going to anything larger than 33s, 5.29s are what i would go with
