Mean Green MG1391SHD 375 Amp High Output Alternator for 6.7L Cummins
Upgrade your 2007.5–2023 Ram/Dodge 6.7L Cummins with the Mean Green MG1391SHD high-output alternator.

Built for Serious Power and Durability
Mean Green engineers this alternator with a tool-steel rotor shaft supported at both ends by heavy-duty, double-sealed bearings. The solid copper stator windings are sealed with high-temperature insulation, and a heat-resistant multi-function integrated regulator keeps performing in extreme conditions. The result is up to 300% more charging power than a stock unit, precision balancing for smooth operation, and the ability to support demanding electrical setups without the voltage drop or charging problems common with factory alternators.
