The 250 amp Ford Motorcraft type 6G series high amp alternator requires a Quicktifier Remote Bridge Rectifier because the output is to great for a single bridge rectifier. Please make a Quicktifier selection when ordering your high amp 6G series alternator. If you order a 6G series alternator at over 200 amps without a second set of diodes, it will fail more quickly , 6G series bridge rectifiers are not heavy duty enough to handle the excessive amperage alone .
Note: You must include, Year, Make, Model and Engine type in the note or comment box when ordering, If you do not let us know your vehicle info it will hold up your order.
Whenever possible it is best to upgrade from the Small Case 6G series Alternator to the Large Case unit. The Large Case Alternator gives you more power at idle, absorbs and dissipates heat better and will last longer at higher amperages. The Large Case Units bolt directly in place of the small case and the plug is the same. Unfortunately, not every mounting style developed by Ford Motor Company comes in both Small Case and Large Case Style. The most common Large Case upgrade is in Ford's F and E series pick-up trucks and vans, as well as, Excursions, Explorer and Expeditions and Mercury Mountaineer (Figure 2, left center). Many Ford trucks came standard with the Small Case alternator and can be upgraded to the Large Case unit or better performance. Other mounting styles only available in the Small Case unit are the vertical "6-12" mount and was featured on Some Ford and Mercury trucks & SUV's, Mustangs etc (Figure 3, right center). The second is an offset or "2-foot" mount, which is common to various Ford and Lincoln vehicles (Figure 4, upper right). The final mount is common to various Ford and Mercury vehicles, it is a "Dual-Ear" mount that has mounting tabs on both the Drive-End (front) and Slip-Ring-End (rear) of the alternator (Figure 5, right). All of the small case alternators are available in the same amperages as the large case and can be ordered below. Just be sure to include your vehicle's year, make, model, and engine size during the order process. If a large case unit is available for your vehicle we will send the large case unit. The Quicktifier remote bridge rectifier is recommended on 200 amp units. Unfortunately, we cannot at this time offer the 250 amp variant in the small case form factor. If your not sure if your Ford Motor Company vehicle has a large case unit upgrade just call and we can tell you.

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.
