Why do I need a shorter belt for High Amp Alternator?

JS Alternator Alternator

Slipping belt – Each of our high output alternators come with smaller overdrive pulley. This pulley is made to increase low RPM charging for maximum output. It is custom for the diameter of the overdrive to be less than your factor pulley, depending on the kind of vehicle you own. If the belt provided does not suffice, you may get the right length from your local parts store. In using the belt and the pulley system, ensure that each part of the pulley system is free of oil or grease, this will help its efficiency.
