GM Mega Amp - Wide Ear CS-144 Replacement - 7.2" Mount

This Mega Amp custom billet aluminum case alternator will be a direct bolt-in replacement for the GM 15SI, 17SI, and CS-144 series alternators. They will have a distance of 7.2" between the two front mounting ears. The case size of our alternator will be smaller in diameter and depth than the factory unit allowing for fitment in tight spaces.
