Ford Lincoln Mercury Y Mount 4.6L 5.4L 6G Rectangular PCM 3 Wire Plug 14.8V 250-390 Amp Brand X High Output Alternator

Sold by AudioSellerz.com.

If you need a high output alternator for your Ford, Lincoln, or Mercury 4.6L or 5.4L setup and want a direct bolt-on solution, this Brand X alternator is built for exactly that kind of upgrade. This model fits PCM controlled applications that use the factory 3 wire connector, giving you a strong charging upgrade for car audio, added accessories, or heavier electrical demand without turning the install into a custom fabrication job.

This alternator lineup is offered in both small case and large case versions with 6 rib and 8 rib pulley options, so you can choose the configuration that matches your vehicle correctly. Available options on this listing include 250 amp small case, 320 amp small case, 270 amp large case, and 390 amp large case versions. All units are designed to bolt on and plug in direct with the factory connector or the included adapter.

If idle output matters, this setup gives you solid real-world charging performance. Small case models produce around 150-170 amps at idle depending on idle RPM, while large case models produce 200+ amps at idle depending on idle speed. Peak ratings are at 1800+ RPM, which makes this a strong fit for customers who want stronger charging support at both idle and cruising engine speeds.

Important Installation Notice
A Big 3 upgrade is required when installing a high output alternator. Factory wiring is not designed to support the increased current demand of a high amp alternator or heavy duty alternator upgrade. Failing to upgrade the charging and ground wiring can create excessive heat, voltage drop, and alternator damage, including rectifier failure. Damage caused by improper wiring or failure to complete the Big 3 upgrade is not covered.

Important Product Information
Brand X high output alternators are hand-built in Ohio and bench tested before shipment. Every unit is built for your specific vehicle and application. If you are upgrading to an aftermarket alternator for car audio or performance use, proper wiring and installation are essential.

Each new unit includes an output sheet, voltage operating range, and installation directions. Every high output car alternator is tested before it ships to help ensure proper performance.

All alternators are supplied in their standard factory color unless custom powder coating is requested. Please note that the alternator shown in product photos may feature a custom color and may not be the exact color you receive unless that finish is specifically requested.

Warranty Information
All new units include a lifetime warranty on labor for repair and rebuild service. The customer is responsible for the cost of any parts needed for the repair or rebuild.

Important Ordering Information
Because each alternator is custom-built to order, average build time is typically 2–4 weeks before shipment.
