Fits the 7.3L Power Stroke in 1997-1998 Ford Super Duty trucks. 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: 7.3L OBS
Vehicles: Ford Super Duty F250 F350
This Robust 370 amp Elite series alternator cranks out 200+ amps at idle with great durability. Full 370 amp output is achieved at anything above 1800 RPM engine speed. Twin rectifiers, 6 phase hairpin stator technology and 12 massive diodes ensure great cooling even in hot climates,
NOTE: For best performance this unit will require the installation of a 1/2 inch to 1 inch shorter than stock length belt. (not included)
