Detailed Description

MPA Electrical 8116603N is an alternator replacement for 1992-1996 Chevrolet and GMC vans and related models, including Chevrolet Astro, Chevrolet G10, Chevrolet G20, Chevrolet G30, Chevrolet Express 3500, GMC Safari, GMC G1500, GMC G2500, and GMC G3500. It is built around the listed Delco configuration and matches the electrical and pulley specifications needed for vehicles equipped with a 105 amp alternator setup. For buyers searching for a 1993 Chevrolet G10 alternator, a 1996 Chevrolet G30 alternator, or a 1996 GMC G3500 alternator, this unit provides a direct-spec replacement path.

MPA Electrical’s New line identifies this as a fresh replacement component rather than a remanufactured unit. The part number 8116603N should be matched to the vehicle’s original alternator specifications, especially pulley groove count, plug clocking, and amperage rating.
