Review on ACDelco 334 2529A Professional Alternator Remanufactured by Matt Eason

Installed on '05 Silverado 2500HD Diesel. Replaced an AD230 alternator with a 105 amp alternator that was OEM and had 200,000 miles, probably 1/2 of that mile when towing a trailer. This remanufactured DR44 AD244 alternator rated 92 amps at idle with the electrical system on, the OEM alternator rated 55 amps under the same conditions. Fitment was cramped, body larger than stock, but it fit, it was an option for this truck. Electrical connections were easy - plug and play. This alternator requires a 3/4" longer belt - Dayco 5061185 Serpentine Belt or other brand.
