Billet aluminum alternator pullies are a great way to keep charging at low RPMs and keep you from frying your alternator at high RPMs. Available in underdrive or overdrive (Using your outside diameter for reference). These pullies fit 5/8" (.625) diameter shaft with keyway and retaining bolt. Match these with our other billet pullies
Can you recomend a high Amperage Alt. that your double billet pulley will fit on that meets the requirements above?
