Ford Motorcraft Type 6G High Output Alternator
Replace your Failing Alternators with our 100% NEW Heavy Duty 6G Series Alternator
Stock Alternators Failing You?
Special Note to Ford Powerstroke Diesel Owners
How often has your standard output Ford Motorcraft type 6G series alternator failed you? Tired of rebuilding your unit because of burnt out bridge rectifiers? The bridge rectifier is, after all, the most common point of failure on an alternator under load. Winches, stereos and complex electronic equipment will require more power than your standard output alternator can handle. So get rid of your under cooled 3G series alternator, or your underpowered small case 6G series alternator.
Upgrade to our heavy duty 6G series high output alternator available in 140, 160, 200 and 250 amp models. Using the newly developedQuicktifier Remote Bridge Rectifier System (click here for more information) based on technology from the Extreme Duty Dual Rectifier CS144 with over eight years of of experience in the field. We can now provide the toughest 6G series alternator with a heavy duty bridge rectifier combined with either the 210 amp or 420 amp external bridge rectifier for extra durability.
Features of The Heavy Duty 6G Series High Output Alternator
- Large fans for increased cooling and life
- Large rear bearing for smooth running
- Heavy duty options have a copper bridge rectifier
- Optional Quicktifier Dual and Triple Bridge Rectifier System attached for better durability

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.
Quick Start now gives you a 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. 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.
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. 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.

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 40 and 50 amp diodes, the heavy duty rectifier uses 70 amp diodes.
