The GT-500-270XP High Output Alternator for Ford Mustang with 5.4 DOHC from Nations Starter & Alternator provides the massive charging capacity your supercharged Shelby requires for peak performance.
- Massive 270-Amp Peak Output featuring an advanced 6-phase hairpin stator for extreme efficiency.

- Severe-Duty Construction with 12 press-fit 50-amp diodes and oversized premium bearings for longevity.
This high-output alternator kit is the ultimate power foundation for GT500 owners running high-draw upgrades like dual fuel pumps, high-velocity intercooler fans, and aftermarket audio systems. Unlike a standard commercial alternator, the 270XP is specifically engineered for "brute force" idle delivery, ensuring your voltage remains stable at 14.8V even during heat-soaked conditions. As a premium upgraded alternator, it features a proprietary digital regulator that integrates seamlessly with your Mustang's PCM to maintain factory temperature compensation and lamp monitoring. By utilizing these high amp alternators, you eliminate the dimming lights and electrical "lag" common when pushing the 5.4L DOHC engine to its limits. Order today.
