Important Before Ordering:

This high output alternator is sold in the standard factory color unless custom powder coating is selected before checkout. Product photos may show a custom color or finish for example purposes only. If you do not select custom powder coating, your alternator will be built and shipped in the standard factory finish.

This alternator is hand-built, bench tested, and shipped after production is complete. Average build time is typically 2-4 weeks before shipment. Because each alternator is built to order for your vehicle and application, it does not ship immediately after purchase.

Please make sure all vehicle information, amperage options, plug type, and any custom options are selected correctly before placing your order.

Important Installation Notice
A Big 3 upgrade is required when installing a high output alternator. Factory wiring is not designed to support the increased current demand of a high amp alternator or heavy duty alternator upgrade. Failing to upgrade the charging and ground wiring can create excessive heat, voltage drop, and alternator damage, including rectifier failure. Damage caused by improper wiring or failure to complete the Big 3 upgrade is not covered.
