When changing the pulley combo on your 03-04 Cobra you will also need to make sure that you have the proper length belt. If you happen to put to large of a belt on you will end up getting belt slip which in turn will rob you of horsepower. Lethal Performance recommends Gates belts as they work very well with Non-Slip and Regular Supercharger Pulleys. We usually have all sizes in stock and ready to ship. If you have any questions about what belt size you need please refer to :
