New belts every 2yrs/12,000 miles is BS!! I just replaced the stock belts on the SS this weekend at 12,205 and they were absolutely fine!! Yea yea, I know about the whole warranty thing...I'm just saying these belts are capable of a lot more. The factory belts were the red lettered one's with Gates written righ on the side. (replace with the same thing) You could still read my old belts. No dryness, cracking, signs of wear or fatigue ANYWHERE. But, for the peace of mind, I changed them. Oh well...
