all i have to say is wow i purchased a 2009 yamaha nytro used with this ski package on it already and the machine handeled great but i had to ask my self is it really the skies ? after loosing my ski rubber on the one ski and the previous owner not supplying me with the correct wrenches to remove the ski i had re installed the stock skies and spindals i had left out on a ride and could not wait to get my spit rails back on. the machine push steer like crazy picking the inside ski up all the time it was terrible felt like i was driving a bus as soon as i got back i got on the phone and called up the fellas at split rail to order the correct wrenches needed as well as my ski rubber the guys there were very helpful in assisting me with my needs .. thanks split rail truly a great design .
