GM 12SI Smooth Look™ 150-Amp Alternator (V-Belt, Baffle/Cone) by Powermaster®

Blended contours, hidden case bolts and teardrop detailing keep the charging system visually clean.

This Powermaster® Smooth Look™ alternator blends the edges of its 12SI-style housing and conceals the case bolts for a clean, rounded profile. Teardrop-shaped surface details give the alternator a finished appearance in an exposed engine compartment. A custom fan, baffle and nose cone complete the front assembly. Its 150-amp rating includes 100 amps at idle, helping support charging and accessory loads at lower engine speeds. An internal regulator permits one-wire or compatible three-wire operation, and the single-groove V-belt pulley is included. Each alternator is individually dyno-tested. Conversions from an externally regulated alternator require the appropriate wiring changes, not reuse of the external regulator.

• GM 12SI-style charging applications; see full fitment list below • Output: 100 amps at idle, 125 at cruise and 150 at top end • Internal 12V regulator; one-wire or compatible three-wire operation • Included single-groove V-belt pulley • Custom fan, baffle and nose cone included • Blended housing contours, hidden case bolts and teardrop surface details • Finish choices: chrome, polished • Individually dyno-tested to document charging output
