Product Description

The ATG11188 High Output Alternator is an aftermarket replacement designed for compatible automotive charging systems. It is rated at 250A with a 14.5V output specification, making it suitable for applications requiring a high-output alternator. Confirm the original alternator configuration and vehicle requirements before installation.

This alternator cross-references Delco part numbers 10463027, 10463095, 10463120, 10463195, 10463204, 10463213, 10479855, 10479907, 1101183, 1101349, 1101454, and 1101604, as well as Lester numbers 7864-5, 7911-5, 7978-5, 7994-5, and 8124-5.

The supplied fitment information includes selected Buick Regal, Cadillac Fleetwood, and Chevrolet Caprice applications. The product title also references the Pontiac Firebird with a 3.8L engine, but the supplied fitment table does not confirm its model year or exact configuration. Verify the original part number, amperage, mounting points, and pulley setup before ordering.
