*Attention!* This is a Computer-Controlled Charging System
- This alternator uses the vehicle's factory computer (ECU/PCM) to control charging voltage, so voltage will continue to follow the factory system behavior.
- This high-output alternator still provides the increased amperage you purchased, delivering stronger performance under load and faster battery recharge.
- Some voltage fluctuation is normal on these systems and does not indicate a problem.
- If fixed or higher voltage is required, please contact our support team for details on a stand-alone alternator configuration with our bypass module to control the battery light.
Installation Notes:
This unit comes equipped with a smaller 1.75 inch diameter alternator pulley, and will require a slightly shorter drive belt for proper belt tension. Not recommended for sustained use above 5,000 RPM engine speed.
The 370 amp E series alternator for Ram pickup with Hemi engines is a direct bolt-in replacement for the OEM alternator, and cranks out over 180+ amps at engine idle RPM, with 370+ amps at cruising speed. This unit features hairpin 6 phase technology and 12 huge press fit diodes diodes for excellent durability. NOTE- A slightly shorter than stock length belt may be required for installation.
