|  Calculating gear ratio question I have a gear reduction unit of 1.6:1 and my clutch/spur is 8:1. What is my new gear ratio? Do I add or multiple them to get my end ratio? thanks |

| Re: Calculating gear ratio question Multiply, but you still need to multiply your internal tranny ratio and your axle ratio to get your final or end ratio. |

| Re: Calculating gear ratio question If you have the gears set up in a reduction direction, then your new gear ratio would be 12.8:1. This is done of course by multiplying the ratios together. -Sam |

| Re: Calculating gear ratio question What kind of tranny are you using? What axles? What pinion/spur? Give out a bit more details and we could probably help you find a final answer. |

| Re: Calculating gear ratio question ok, here is what i got.... x factor axles, emaxx tranny(still using 1 & 2 gear), 72 tooth spur, 9 tooth pinion. as of now I use 1st gear only cause 2nd is still too high for my needs. I like 1st gear for bumping up a rock but would like an even lower gear for slow crawls. so i'm trying to make 2nd gear have the same ratio as my 1st gear is now by using a gear reducer. I looked up the gearing and there is a 1.6 difference between the tranny's 1st and 2nd gear so that leads me to believe i need a 1.6 reducer to make this happen thanks guys |
