DURABILITY & RELIABILITY

Delco Remy Heavy Duty Brushless Alternators have fewer moving parts. Fewer moving parts mean less wear on the alternator. Alternators pull air through from the back to the front in order to cool the internal electronics which introduces dust into the alternator. With a brushless alternator, there are no issues of dust hanging up brushes and causing early failure. Without brushes, there are 13 fewer moving parts, eliminating components that wear out, while extending overall product life. All major internal components that carry current such as a field coil, regulator, bridge, connectors, and stator, are stationary components and more resistant to vibration and debris
