JS Alternators for Ford F550 Super Duty V8 6.7L (2011-2022) Single Alt Only - High Output 250 / 320 amp
JS Alternators for Ford F550 Super Duty V8 6.7L (2011-2022) Single Alt Only - High Output 250 / 320 amp
Fitment:
This is a direct fit high-output alternator for the 2011-2022 Ford F550 Super Duty 6.7L. Being a direct fit, this alternator fits directly into your stock alternator location.
Plug:
This high-output alternator comes with a factory style plug so that your OEM plug will plug directly into the alternator. Therefore, with an OEM style regulator, it will have a factory voltage set point.
NOTE: If you require charging at a certain voltage setpoint, we offer a selection of different voltage regulators that you will need to purchase with the alternator for it to be installed. View our Regulator Options Here.
Pulley:
This alternator also comes with a 54mm pulley in which you will use factory 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.
