High Output Alternator 250 Amp 6-Rib Serpentine Pulley

The JS Alternators 1999-2004 Ford F-450 Super Duty V10 6.8L High Output Alternator is engineered to provide superior electrical output for demanding applications. Its high-output capability makes it ideal for systems with heavy electrical loads, including performance car audio setups, marine use, and racing vehicles. Key features include a robust 250 amp output capacity and a 6-rib serpentine pulley designed to spin faster, maximizing energy production. The alternator comes with a smaller pulley, which necessitates the installation of a 1/2" to 1" shorter belt for proper tension. For optimal performance and safety, a Big 3 Wiring Upgrade Kit is required when installing any high-output alternator. It is recommended to use 1/0 gauge 100% copper wire for this upgrade to ensure the electrical system can safely handle the increased output. Additionally, if a specific voltage setpoint is required, a compatible voltage regulator must be purchased separately. This high-output alternator is specifically designed for the 1999-2004 Ford F-450 Super Duty models equipped with the V10 6.8L engine.
