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 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: 6.7L
Vehicles: Ford Super Duty F250 F350
Newly redesigned for 2020, The Elite series offers the highest possible amperage and durability available in a large case alternator. 6 phase technology combined with massive twin rectifier assemblies and 12 diodes makes these alternators totally durable for daily use, while still maintaining 200+ amps at engine idle speeds. NOTE: F250/F350 6.7L Diesel trucks were available with single or dual alternator configurations. This unit fits the single or the lower dual alternator mount. It does not fit the upper 157 amp factory unit.
