Description
xPart Overview
The 11792 180A High-Output Alternator is a heavy-duty replacement unit for the 2014-2020 Ram ProMaster 1500 / 2500 / 3500 vans equipped with the 3.6L Pentastar V6. The 180-amp output is well above the OE spec, giving fleet operators, ambulance builders, RV upfitters, and accessory-heavy builds the extra charging headroom needed to keep refrigeration units, inverters, lighting, and comms gear topped up — even at idle.
Direct-fit replacement for the original 220-Amp / 180-Amp OE alternators, with the same mounting geometry and pulley alignment. Add to Quote at KOEEP and our team will confirm pulley type (6-groove / decoupler) and ship globally.
