Ford Diesel Alternators


  HIGH OUTPUT ALTERNATOR Large Case Upgrade for 1999 & up Ford 7.3L, 6.0L & 6.4L

 In 1999 Ford Motor Company switched from using the large case 3G alternator on the 7.3L PowerStroke Diesel to the small case 110 amp 6G series alternator. After 99 Ford no longer offered the large case alternator upgrade option for powerstroke 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.

Quick Start now gives you a better third choice with our LARGE CASE 6G alternator upgrade that bolts directly into your existing 110 amp small case bracket. You can't get this large case option from you local auto parts store or Ford Dealer because Ford Motor Company did not offer the large case alternator for the Ford 7.3L, 6.0 or 6.4 PowerStroke Diesel F series truck, Excursion and other vehicles with the PowerStroke Diesel.
With the large case alternator you will see substantial improvement in idle or low speed charging power output plus the large case alternator is much more reliable at higher outputs compared to the small case unit.

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 amperage and duty ratings. 

WHY OUR ALTERNATORS ARE BETTER    

These alternators are built in the U.S.A. from all brand new top quality components, such as: Ford O.E. NTN bearings from Canada,  Ford O.E Motorcraft or Taditel voltage regulator/brush assembly,  Heavy Duty Bridge Rectifiers with 8 high amp diodes (which are better than 6) pressed into a copper heat sink compared to the standard aluminum heat sink. The heavy duty rectifier also has a larger 8mm copper plated battery post for better power distribution. The Heavy Duty Rectifier is from an O.E. supplier to GM in Anderson Indiana,  Stators are wound in Georgia and the metal stator laminations from Chicago.  We try to incorporate many original equipment Ford Motorcraft alternator components when possible.

Note: The difference between the Standard Duty and Heavy Duty alternators listed below is in the amperage rating of the diodes in the bridge rectifier.  Alternators make AC current, then use a Bridge Rectifier with diodes in it to convert the AC current to DC current for use by the vehicles electrical system.
The Rectifier is the #1 component to fail in high power demand situations. The standard duty rectifier uses 55 amp diodes, the heavy duty rectifier uses 70 amp diodes
, in a solid copper heat sink for better heat & electrical conductivity plus a larger copper plated 8mm battery post that is silver soldered into the copper heat sink. This is the best high amperage bridge rectifier on the market.
The Quickifier Remote Bridge Rectifier System shown in "related products" can be attached to any of these alternators for more power and greater reliability.
