Got a dead alternator in your 2002 Chevy Avalanche 1500 with the 5.3L?
This HYRO replacement is exactly what you need.

It's a brand-new unit, not remanufactured, pumping out 130 amps of reliable power.
Built to OE specs, it's a direct bolt-in with clockwise rotation and a serpentine pulley included.

It replaces a ton of part numbers like 321-1803, 321-1813, and 10464405.

No core charge, no hassle.

Just pull the old one and install this bad boy.
