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!


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.

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.
