This SBC heavy-duty alternator generates a maximum of 303 Amps at normal driving speeds and produces 209 Amps at idle. The SPX series of SBC alternators are assembled using DENSO components and produce the highest idle output. They feature larger housing while still retaining OEM fitment without any modification required.
They run cooler and are virtually indestructible. This alternator is designed to be an exact replacement to the OEM primary alternator for the Sprinter 3.0L gasoline engine (OM 642) and will directly bolt-on with no modifications necessary. A precision machined, hard anodized pulley made from Aircraft Certified 6061 aluminum is installed on each alternator for maximum output and durability.
This alternator comes with an unprecedented full two year warranty.
