250 Amp Ford Motorcraft Type 6G Series High Amp Alternators

With Heavy Duty Dual and Triple Bridge Rectifier with heavy Voltage Regulator

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 .

This unit is built in the USA with NTN bearings which are the OE Bearings used by Ford, Heavy Duty Bridge Rectifier inside the Alternator rated at 210 amps, Stators from Georgia, Heavy Duty Voltage Regulators and all top Quality Components. The 250 amp Alternator cannot be made in a single bridge rectifier because the 250 amp output exceeds the durability rating of the 210 Amp rated single bridge rectifier.

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.  FSeries, E Series, Excursions, Explorer and Expeditions and Mercury Mountaineer  with the power Stroke Diesel Motor Many Ford trucks came standard with the Small Case alternator and can be upgraded to the Large Case unit or better performance. 

 


Special Note to Ford Powerstroke Diesel Owners

1998 and Older Ford 7.3L Power Stroke Diesel uses the 3G Series Large Case Alternator. Click Here for the 3G Series Heavy Duty High Output Alternators.

After 1999 Ford no longer offered the large case alternator upgrade option for Power Stroke diesel equipped vehicles. The Standard Alternator was the small case 110 amp 6G series alternator on the Power Stroke Diesel. Since 1999 the small case was the only choice and has been plagued with reliability issues. WE HAVE THE SOLUTION WITH THE LARGE CASE 6G UPGRADE UNIT THAT FITS IN THE SAME MOUNT, USES THE SAME BELT AND PLUGS DIRECTLY IN TO YOUR EXISTING PLUG.
"NO ADAPTER HARNESS NEEDED"

Large Case 6G Series Alternator vs Small Case

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.

 

Why Not Upgrade?

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 and mounting styles. Plus, our alternators are brand new using nothing but Top Quality Components.
