GM's AD244 series High Output Alternators
Delphi AD-230 to AD-244 Alternator Upgrade.

The AD series Alternator with the 2 prong Voltage Regulator can replace the 
DR44G Alternator found on many late model GM vehicles.

Also, the Large Case AD244 with 4 pin voltage regulator can replace GM's Small Case 105 amp CS-130D alternator with the same mounting type.

Avalanche, Silverado, Escalade, Yukon, Suburban, Sierra, Trailblazer, Tahoe, Any Late Model Vortec V-8 and more!


When ordering high amp alternator, check the plug on your existing alternator to see 
if it has a two pin or four pin connector at the plug and specify which it is in the customer comments box

*GM first started using the AD series alternator on some 1999 selected models. You should check to see if you have the CS series or the AD series on your vehicle. Your CS130D alternator mount will look like the one shown below.

Our brand new AD series AD-244 type alternators are constructed using the highest quality components available. The larger AD-244 alternator produces more power at lower engine speeds compared to the smaller AD-230 or any other small alternator. Plus the larger AD-244 alternator is much more reliable at higher amperage output and extreme loads. We have made great improvements to the design of our AD-244 alternator. It is by far the best high amp alternator available on the market today. Our continuous development and striving to be the best will assure you'll receive an alternator with unsurpassed performance and durability.

The Larger AD-244 will bolt directly in place of your existing 100-105 amp AD230 alternator without any modification. It is recommended that you upgrade the battery wire that connects to the rear of your alternator. You need a bigger wire to get the power out of the alternator and into your battery and electrical system. Our new generation of AD-244 are equipped with a heavier "copper" heat sink rectifier and oem quality regulators that just do not go bad! Along with perfectly balanced rotor and stator combinations for the best performance.



ad244 comparison front

Standard OEM AD-244 series alternators use 55 amp diodes in the bridge rectifier. In our top quality Heavy Duty AD-244 type alternators we use rectifiers that have 70 amps diodes. Our Extra Heavy Duty version uses the toughest rectifier in the industry consisting of: larger 8mm copper plated battery stud that is silver soldered to the solid copper positive rectifier heat sink, making it much more durable over the standard version.





When ordering, specify whether fit is for 2 pin or 4 pin plug, 
You must pull the plug and look inside the connection to see if it's 2 or 4 pin, you cannot just count the wires going to the alternator.

Why we believe the AD244 series alternator is better than the DR44 & DR44G alternator for High Output Alternators on 05 and newer GM vehicles.
The DR44G alternator was used on most GM vehicles after 2005, most DR44G alternators use the 2 pin plug voltage regulator.
The DR44G and AD244 alternator are almost identical except that the bridge rectifier on the AD series is a replaceable component 
where on the DR44G alternator the negative part of the bridge rectifier is built into the rear housing ,so if your negative diodes fail, which they do often, you must replace the complete rear housing, but on the AD series alternator you can just replace the bridge rectifier, and the bridge rectifier fails quite often on high output alternators.

These are 100% NEW Alternators complete with pulley using Top Quality Components so there is NO CORE CHARGE...
 

NOTE: ALL THE AD SERIES ALTERNATORS CAN BE ORDERED AS A STANDARD OR HEAVY DUTY ALTERNATOR WITH ONE BRIDGE RECTIFIER INSIDE THE ALTERNATOR OR YOU WILL BE GIVEN THE OPTION, WITH A DROP DOWN MENU,  OF ORDERING THE STANDARD AND HEAVY DUTY ALTERNATORS WITH THE QUICKTIFIER 210 AND QUICKTIFIER 420 EXTERNAL REMOTE BRIDGE RECTIFIER SYSTEM FOR GREATER RELIABILITY. 

YOU WILL ALSO CHOOSE IF YOU WANT THE 4 PIN OR 2 PIN VOLTAGE REGULATOR.
