Our take on the 1986-1997 Ford F-350 V8 7.5L High Output Alternator

This is a direct-fit high-output alternator for the 1986-1997 Ford F-350 with the 7.5L V8. It bolts into the stock alternator location and comes with an adapter plug that mates the new unit to the factory harness, so no rewiring is needed. A smaller pulley spins the alternator faster to reach its full output, which means you must fit a belt 1/2 to 1 inch shorter. It suits owners running winches, plow lights, big audio or dual batteries who have outgrown the stock charging system; it is not a stock-replacement part for a truck that only needs to keep its original battery topped up.

About the 1986-1997 Ford F-350 V8 7.5L High Output Alternator

This is a direct fit high-output alternator for the 1986-1997 Ford F-350 with the 7.5L V8. It installs in the stock alternator location.

It comes with a separate adaptor plug. One end plugs into the high-output alternator and the other end plugs into the factory plug.

It also comes with a smaller pulley, which makes the alternator spin faster than a larger pulley would. This helps it produce its maximum output. With the smaller pulley, a belt that is 1/2" to 1" shorter is required.

Questions and answers

Does it bolt straight in?
Yes. It is a direct fit for the 1986-1997 F-350 7.5L and mounts in the stock alternator location. The included adapter plug connects the alternator to the factory harness.
Why does it need a shorter belt?
The smaller pulley spins the alternator faster so it reaches maximum output sooner. That smaller diameter means you need a belt 1/2 to 1 inch shorter than the stock one.
Can I set a specific charging voltage?
Only with a separate regulator. The alternator ships with its standard regulator, and other voltage setpoints are sold as add-on regulator options that must be bought with the alternator.
Will it fit a 7.3L diesel or a gas 5.8L?
No. It is listed for the 7.5L V8 in the 1986-1997 F-350. Check the engine and year before ordering.
Do I need to upgrade the charge wiring?
A high-output alternator pushes more current than the stock one, so inspect the charge cable and grounds. Many owners upgrade the main charge wire to handle the extra output.
