Looking for some front shocks for my Sno-x Viper, Although I don't want them too stiff. Need to be 20" center to center. Anyone have a good set they want to sell? Thinkin of either floats, walker evans, or air 2.0. What would be the best shock for an agressive trail rider? What are the center to center on some of these race sled? Polaris, ski-doo, Cat....
