Detailed Product Overview

WAI alternators are built to deliver the amperage required by modern vehicles, and the 8292N-DR220A follows that approach with a 220 amp rating and proprietary manufacturing processes aimed at long service life. This unit uses an internal regulator, internal fan, and clockwise rotation, with the pulley included for a direct replacement setup on supported GM platforms. The WAI 8292N-DR220A is a practical choice for drivers looking for a high-output alternator for Chevrolet Silverado, GMC Sierra, Chevrolet Avalanche, and related applications.

This part cross-references AC Delco 8292-220 and 10464405 for the same application.

Common Problems This Alternator Can Address

Installation Notes and Tips

Verify pulley groove count, serpentine belt routing, rotation direction, and connector style before installation. Confirm the vehicle uses the AD244 Series 220 amp upgrade application listed for your exact year, make, and model. For Chevrolet Silverado 1500, GMC Sierra 1500, and Chevrolet Express 1500 applications, compare the original unit to the WAI 8292N-DR220A before removal to ensure proper fitment.
