Installation notes: This unit comes equipped with a smaller 1.75 inch diameter alternator pulley and requires a slightly shorter drive belt for proper belt tension. It is important to note that this alternator is not recommended for sustained use above 5,000 RPM engine speed. Using the incorrect shorter belt can result in low or no output, as well as create extra workload for the alternator.

The cast housing Elite series of alternators offers the highest possible amperage and durability available in a large case hairpin alternator. With 6 phase technology and massive twin rectifier assemblies with 12 diodes, these alternators are built to withstand daily use while still providing excellent output. Even at engine idle speeds, this alternator cranks out over 200 amps, and at cruising speeds, it delivers a full 320+ amps at full temperature.

This alternator utilizes the more robust 4-pin style regulator, bypassing the RVC charging system found in all 2005 and later GM truck applications. It includes a 1-wire P101 harness that needs to be installed to a tested 12V switched source, and a P103 module that plugs into the vehicle's 2-pin original alternator wiring harness. This setup eliminates extreme voltage fluctuation, check battery lights, and computer-controlled voltage swings. You get the voltage you need, when you need it.

The 320 Amp High Output Alternator is compatible with various GM truck models spanning from 2005 to 2013. Whether you own a Cadillac Escalade, Chevrolet Tahoe, GMC Yukon, or Hummer H3, this alternator is designed to fit your specific make, model, engine size, and year.

Choose the 320 Amp High Output Alternator 05-13 GM Truck for exceptional performance, durability, and reliability. Upgrade your GM truck's charging system and enjoy a consistent and powerful output for all your electrical needs.
