Our lightweight alternator and bracket conversion kit frees up a few extra pounds. This complete kit contains a modern, internally regulated lightweight and compact Denso 60 Amp alternator, as well as the mounting spacers, brackets and bolts necessary to retrofit this alternator onto your big block Mopar. And since these are internally regulated, you can simplify your wiring by getting rid of that factory firewall mounted voltage regulator. We even include the single groove pulley on the alternator! A nice clean looking setup that will make your car stand out from the pack... and at a great price!
