In 1999 Ford Motor Company switched from using the large case 3G alternator on the 7.3L Power Stroke Diesel to the small case 110 amp 6G series alternator. After 99 Ford no longer offered the large case alternator upgrade option for power stroke diesel equipped vehicles. Previously, to get more charging power for your 7.3, 6.0 or 6.4 diesel your options are either, dual alternators or upgrade your existing small case alternator. The problem with upgrading your existing small case alternator is that they tend to be less reliable when upgraded. Plus with an upgraded version of the small case 6G alternator you will not get extra power at lower engine speeds, all the extra power is when you rev the motor.
So if you need more charging power or your alternator is getting old and tired why not upgrade to the superior large case 6G series alternator. We have the 6G large case alternator in several amperages and duty ratings. Plus, our alternators are brand new and incorporate many original equipment Ford Motorcraft alternator components when possible. Click here to see a partial list of common vehicle applications.
