6.0 Powerstroke High Output Alternator – Mean Green 8306 (2003–2005)

The Mean Green 8306 is a direct bolt-in high-output alternator engineered for 2003–2005 Ford 6.0L Powerstroke diesel trucks. It delivers 220 amps at 2,000 RPM and 110 amps at idle—up to 300% more charging capacity than the factory unit—making it an excellent upgrade for trucks running extra electrical loads such as upfitter equipment, auxiliary lighting, dual battery setups, or heavy accessories.
