The ratios I have are 2.7, 3.8, 10.38. I use them all around here. 2.7 you already have and is a good trail ratio. 3.8 is a great rock ratio, but is too slow for most trails. 10.38 is really slow, 11 mph with a 30% overdrive for anything but large rocks. But is really great then because you can just idle through the big ones. No deals on quantity though. They build each one custom order
