I am looking at purchasing a clutch for my 03 pro x 700. I have found a new clutch that has no spirng or weights for the right price but the part number 1321880 references the prox 800 and the 700 number is 1321810. I have talked to polaris tech dept and they said don't use it, but couldn't tell me what was different beyond the fact that the spider covers a bigger area for better wear. They couldn't identify any other changes. Does anyone have any experience in the clutching department? Does anyone know what is different.
