The Mean Green 1398 is a 220-amp high output alternator for 2003-2007 Dodge Ram trucks with the 5.9L Cummins. It mounts on the stock brackets, plugs into the stock harness and puts out up to 300% more charging power than the factory unit, for trucks running winches, light bars, inverters, audio or plow gear.
Fitment
Listed for the 5.9L Cummins common-rail engine in 2003-2007 Dodge Ram trucks. Mind the year split: a 2007.5 truck has the 6.7L, so this alternator is for the 5.9L 2007 trucks, not the later 6.7L ones. Verify by VIN or call us if you are not sure what is under the hood. More Cummins parts are in the engine hub.
Why this part
Every accessory you add to a diesel pickup draws on the charging system: lift pumps, light bars, winches, inverters, audio and plow gear. Mean Green builds the 1398 as the answer to charging problems on the 5.9L, with up to 300% more power than stock and the output to keep up no matter what the truck's power requirements are. Mean Green points it at ambulances, tow trucks and motorhomes, and at any vehicle running auxiliary lights, winches, stereo systems or other power accessories.
The internals are built for long service. The tool steel rotorshaft is supported at both ends by heavy-duty double-sealed bearings, the heavy-duty solid copper windings are sealed with high-temperature insulation, and the unit is precision balanced for smooth operation. That build is one reason Mean Green includes a 1-year warranty at no charge on every alternator. Mean Green designed it to outlast and outperform any other unit and rates it for a 300,000-mile life expectancy.

Installation notes
Special new castings let the 1398 use the stock bracketry and bolt hole locations, so it mounts where the factory alternator came off. The stock wiring harness can be used too, so it plugs in without rewiring.
