Fits the 5.9L common-rail Cummins in 2003-2009 Dodge Ram 2500 and 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 370+ 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: 5.9L ISB CR
Vehicles: Dodge Ram 2500 3500
The Elite series alternators offer the highest possible amperage and durability available in standard fitment "direct bolt in" automotive alternator. 6 phase technology, combined with massive twin rectifier assemblies and 12 diodes make these alternators totally durable for daily use. This alternator will easily produce 200+ amps output at engine idle RPM, with 370+ amp output at normal cruising speed.
