The hugely popular G series of large case 3 phase alternators have been tried and true for over 15 years. These units offer excellent low RPM output, with 100,000 mile durability. This G series alternator features Mechman's custom solid copper rectifier with large 65 amp press fit diodes and over sized output stud for excellent durability. It cranks out over 165+ amps at just 600 RPM engine speed on any standard GM truck, with full 270+ amps at anything above 1800 rpm engine speed! A 46mm hard anodized billet aluminum 6 rib pulley is used to maximize low RPM output, so a 1/2" to 1" shorter than stock length belt (not included) is recommended for optimum belt tension. 270 amp G series units are made in the USA and come with a 2 year warranty.
