320 Amp High Output Alt For GM Suburban Silverado Sierra Tahoe Escalade 2014-18

Installation Notes:

This unit comes equipped with a smaller 1.75 inch diameter alternator pulley, and will require a slightly shorter drive belt for proper belt tension. Not recommended for sustained use above 5,000 RPM engine speed.

The cast housing Elite series offers the highest possible amperage and durability available in a large case hairpin alternator. 6 phase technology combined with massive twin rectifier assemblies and 12 diodes make these alternators totally durable for daily use, while still maintaining great output. This alternator cranks out over 200 amps at engine idle speeds and a full 320+ at cruising speeds at FULL TEMPERATURE. This alternator comes with a smaller diameter pulley installed on it, and will require a 1/2" to 3/4" shorter belt for proper function.
