*Attention!* This is a Computer-Controlled Charging System
- This vehicle uses a 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
- Custom or fixed voltage output will require ECU tuning.
Installation Notes:
The 240 amp E series alternator for Ram pickup with Hemi engines is a direct bolt-in replacement for the OEM alternator, and cranks out over 200+ amps at engine idle RPM, with 250+ amps at cruising speed. This unit features hairpin 6 phase technology and 12 huge press fit diodes diodes for excellent durability. Fitment Guide:
