Fits the 6.4L Power Stroke in 2008-2010 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 240+ 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: 6.4L
Vehicles: Ford Super Duty F250 F350 F450
This outstanding large case elite series alternator features 6 phase Hairpin stator technology, twin rectifier plates, and 12 massive diodes for outstanding durability. In diesel applications, this unit can crank out as much as 180 amps at engine idle rpm, with 240+ amps at cruising speed. This unit can be installed with the stock length belt, and uses the same beefy internal components as it's 370 amp big brother, to provide excellent durability in abusive applications.
