(1) S-Series 170 Amp Racing Alternator 63 - 85 GM Polished Finish

The S series of 6 phase hairpin alternators offers incredible low RPM output in a compact and durable package. Highly efficient, these units use less horsepower than conventional 3 phase alternators. 12 diodes, twin rectifier plates and outstanding airflow ensure much better durability than standard Delco based alternators, even in severe conditions.

This unit comes with a 2.5" V-Pulley installed and also includes a 2.1" 6 rib serpentine pulley for alternate applications.

This custom designed housing directly replaces standard Delco 10DN, 10SI and 12SI alternators on most 1963 through 1985 GM vehicles. A side output stud and seamless rear cover with a side output plug allow for better clearance from the back of the alternator to the front of the engine and a smooth appearance. A single wire on the provided pigtail gets connected to any ignition switched 12V+ source to turn the alternator on and off with the ignition switch.

Simply run a properly sized positive and ground cable from the alternator to the terminals of the battery and the alternator will work perfectly, regardless of what kind of wiring harness you have. Because of their compact size and standard GM mounting ears, these alternators also work well in many aftermarket or custom bracket installations.
