High-Output 250-Amp Alternator for 1997-1998 Dodge Ram 2500 (BR/BE)
What it Does: The 250-Amp High-Output Alternator replaces the factory charging unit on the 1997-1998 Dodge Ram 2500 to deliver stable, high-amperage electrical current for auxiliary winches, work lighting, and heavy-duty utility loads.
The Stock Dodge Ram 2500 Charging Deficiencies
Factory alternators installed on the second-generation BR/BE chassis were rated at a modest 75 to 136 amps, leaving minimal headroom for auxiliary equipment. Under demanding duty cycles—such as running snowplow hydraulics, winches, or high-draw inverters—the factory rectifier diodes overheat and thermal throttling causes critical voltage drops below 12.5V at idle. This severe electrical starvation accelerates battery sulfation, stresses the PCM, and compromises ignition coil output on both the 5.2L Magnum and 8.0L Magnum powertrains.
The Engineering Solution
Manufactured in the USA, this heavy-duty 250-amp alternator incorporates dense, high-purity copper windings and an upgraded heavy-duty diode bridge engineered to withstand sustained high thermal and electrical loads. Delivering robust amperage output across the entire RPM range, it eliminates idle voltage fluctuation and maintains steady system voltage above 14V. Featuring heavy-duty bearings, a balanced rotor assembly, and direct mounting interchangeability with OE part 56027913, this unit integrates seamlessly with the factory serpentine accessory drive bracket.

Frequently Asked Questions & Fitment Warnings
Does this fit the BR/BE Ram 2500?
Yes, this is a direct fit for the 1997-1998 Dodge Ram 2500 equipped with the 5.2L Magnum or 8.0L Magnum engine.
Do I need to upgrade my main power cabling?
Yes, installing a high-gauge fused charging wire upgrade directly from the alternator output stud to the battery terminal is recommended to prevent line resistance and harness overheating under continuous 250-amp loads.
