Phazer Clutches

I was wondering if I should replace my clutch springs, both the primary and secondary. There is about 10k miles on the sled, and im not sure if they have been replaced before...although ive put probably 2-3k on and have not changed them in that time period. Should I replace them? and if so where should I buy them from?? (denniskirk does not come up with anything for my sled)

I would......it would cost like $50-60.00 Can, so thats probably like $10.00 U.S..lol.....and you can get them at your local snowmobile shop.
