The Newest 24V: Delco Remy 40SI Alternator

The 40SI was designed for high output, high efficiency and long life. From the brushless design to its high temperature ratings, this best-in-class model is now available for 24 volt applications.

“It will fill a void that many of our customers had in the off-highway applications as it gives even higher efficiency and output as well as added durability and life,” says Koehlinger.
