Fits the 6.7L Cummins in 2007-2010 Dodge full-size trucks and 2011-and-newer Ram 2500 / 3500 pickups. This is a direct bolt-in upgrade over the factory unit — same mount, same pulley position, no bracket modification.
Diesel engines spend most of their working life at low RPM, and that is exactly where a stock alternator runs out of headroom. This unit holds 200+ amps at engine idle and delivers a full 320+ amps at cruising speed, hot rated — enough for a lift pump, auxiliary lighting, a winch, a plow, a welder or a competition-grade stereo without watching your voltage sag at every stoplight.
Engine codes covered: 6.7L ISB
Vehicles: Dodge / Ram 2500 3500
This 320 amp, large case hairpin high output alternator features twin finned rectifier assemblies and 12 huge press fit diodes for outstanding durability. These impressive alternators produce 200+ amps at engine idle RPM, (on diesel applications) and 320+ amps at normal cruising speeds AT FULL OPERATING TEMPERATURE. You won't find a more durable high output alternator anywhere!
