Billet Polished 240 amp racing alternator GM truck LS engine swap

The S series of 6 phase alternators offers incredible output in a compact and durable package. 12 diodes, (instead of the normal 6 diodes) and twin rectifier plates with outstanding airflow ensure long service life, even in severe conditions. 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.
