You won’t find a glossy powder coated alternator with marketing flash and sizzle. Sound engineering knows that the powder coating will act as an insulator on the aluminum alternator housing hindering the efficient dissipation of heat, resulting in a burned out alternator. We gave up the flash and sizzle paint job for an alternator that simply doesn’t overheat when combined with it’s optimal dual fan cooling and design features. The alternators come with an industry leading three (3) year limited Warranty!
