This SBC heavy-duty alternator generates a maximum of 320 Amps at normal driving speeds and produces 240 Amps at idle. The SPXi 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 secondary alternator for the Sprinter 3.0L gasoline engine (OM 642) with 12 volt auxiliary circuits and will directly bolt-on with no modifications necessary. It can power auxiliary equipment which requires 12 volt power supply and up to 270 amps. 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.
Note: This alternator is designed to be a direct replacement for the secondary alternator on Sprinter vehicles with a 12 volt auxiliary system. It can also be added to OEM configurations which have only a single alternator setup using the Dual Mounting Bracket.
