B stock alternators are typically sold with a 90 day warranty.
The discounted prices are only valid on our website and do not qualify for any special promos, dealers, distributors or codes. We’re unable to honor these discounts for phone orders or anywhere else as these are meant to be a quick and simple alternator purchase for our customers.
These alternators are built to spec and are not applicable for modifications such as paint, clocking, pulley changes, harness swapping or regulator upgrades.
S Series
The S series of 6 phase alternators offers incredible output in a compact and durable package. Highly efficient, these units use less horsepower than conventional 3 phase alternators. 12 diodes, twin rectifier plates and outstanding airflow ensure long service life, even in severe conditions. The 320 amp model offers the best balance between peak output, and output at engine idle RPM.
NOTE: This alternator comes equipped with a 46mm diameter overdrive pulley that will require the installation a 1/2 inch to 1 inch shorter than stock length belt (not included) for proper belt tension.Notes:
