New alternator For 94-02 Dodge truck with Cummins engine/ Denso alternator.

This is a new Genuine OEM 120amp alternator. No core required. Pulley not included, save by using your old pulley or order a new one below. In 1999/2000 and in 1989 model years two alternators were supplied. This alternator directly replaces the  Nippon Denso alternator. If you have the Chrysler/Bosch alternator you will need to remove the rubber plug and add lugs to the two small wires. The small wires are non-polar and can connect to either lug.

Part# SA3310    New Genuine DENSO alternator as shown above, Sale $359.90, years 1989-2002. 

Part# 10P    New pulley for above alternator Sale $39.90, years 1989-2002.       

Part# SA8201  New brushes with holder for stock Denso alternator,  $26.95/set, years 1989-2002. 

Our experience shows that you can usually replace the brushes in these alternators once, usually around 100K miles. The second time the  alternator should be rebuilt or replaced because the slip ring (where the brushes rub) may be too worn. Your mileage may vary of course. In 1999/2000 and in 1989 model years two alternators were supplied. These brushes only fit the Nippon Denso alternator. If you have the Chrysler alternator these will not fit. Please be sure your alternator is a Nippon Denso before ordering. BRUSH INSTALL INSTRUCTIONS
