JS Alternators for Ford Ranger V6 4.0L (1996-2009) High Output 250 / 320 amp
Fitment:
This is a direct fit high-output alternator for the 1996-2009 Ford Ranger 4.0L. Being a direct fit, this alternator fits directly into your stock alternator location.
Plug:
This high-output alternator comes with a separate adaptor plug. One side will plug directly into the aftermarket high-output alternator, and the other side will plug into the factory plug.
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 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.
See this Blog Article for assistance in finding the correct 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.
