Fits the 6.7L Power Stroke in 2011+ Ford Super Duty trucks. Fits the single-alternator position or the lower unit on dual-alternator trucks; it does not replace the upper 157-amp factory unit. 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
