The AD-244 alternator fits the 4.8L, 5.3L, 5.7L, 6.0L, 6.2L, 8.1L V-8 and 6.6L Duramax Diesel engines for the Tahoe, Avalanche, Escalade, Yukon, Silverado, Sierra, Denali, and Suburban. The large frame AD-244 can also retrofit early model Chevy & GMC Truck & SUV applications for a superior high amp replacement. The Larger AD-244 High amp alternator will bolt directly in place of your existing 100-105 amp alternator without any modifications to the vehicle. 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 Series Alternators are equipped with a heavier "copper" heat sink rectifier and heavy duty quality regulators that just do not go bad! The OEM and Workhorse Series have 75 amp heavy duty diodes. With perfectly balanced rotor and stator combinations for the best performance from every Nations High Amp Alternator. We can't stress enough that our standards of quality are above and beyond our competitors. Proud to say "Made in the USA".
