JS Alternator for GM Billet Standard (1996-2024) High Output 250 / 320 / 370 / 400 amp
Fitment:
This is a custom designed billet high-output alternator for GM Vehicles 1996-2024. Being a direct fit, this alternator fits directly into your stock alternator location. Powder coat options for the front housing are available to purchase with this unit. The back housing will automatically come with a powder-coated black back.
Regulator:
This high-output alternator comes with 7 customized regulator options for you to choose from, as we know you may need to charge at certain voltages. If you have any questions regarding what voltage you need to charge at or which Regulator to choose, please call or email us at 888-245-3680 or questions@js-alternators.com
Pulley:
This alternator also comes with a smaller pulley, which causes it to spin faster than a larger pulley. This can help the alternator produce its maximum output. With a smaller pulley, it is required to install a 1/2" - 1" shorter belt.

Big 3 Wiring:
When Upgrading to a High-Output Alternator, it is required to upgrade your wiring with the Big 3 Wiring Upgrade Kit. It is recommended to use 1/0 100% copper wires for the upgrade.
Why we recommend The Big 3 upgrade.
The Big 3 upgrade is an easy way to improve your vehicle’s charging system by adding three heavier-gauge cables between the alternator, battery, engine, and chassis. These extra cables reduce electrical resistance, allowing power to flow more efficiently throughout the vehicle while minimizing voltage drop under high electrical loads. It’s a common upgrade for vehicles with high-output alternators, aftermarket audio systems, off-road lighting, or other power-hungry accessories because the factory wiring is often a limiting factor. The original wiring remains in place, with the new cables installed alongside it to provide a stronger, more reliable path for electrical current.
