well not posative what youre numbers meen, im running a 4to 1, i think they said it gives a 14% reduction in 2 hi, i bought it 8 years ago so im not sure, it seamed to help a little on the road,dont hit the pavement much anymore, but i ended up changing the axel gears to 5.38 anyway, it did help alot in low range i think the stock setup is around 2 to 1, iim sure sombody who uses theres on road with the same tire will chime in , i know they make a 6 to 1 now, not sure what the 2 hi reduction would be, maybe 20%? that should help quite abit
