As I change the pulley and the motor has a shaft 1 inch higher than it was, I have to buy new belts. I was wondering if stock belts are made with kevlar or another material ? My 926 LE had twin belts kit installed. I never changed the stock belts since this kit was installed. Bearing dealer here can sell kevlar belts for $26 (Can) each. Price is higher than Ariens belts so I suppose Ariens don't use kevlar belts.
