*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.
Features a GM 2-pin RVC connector for seamless integration and optimal performance. Boost your vehicle's electrical system with this reliable and efficient alternator, engineered to meet the demands of modern automotive systems. The 240-amp option offers the best balance of low idle amperage output and 250+ amps of amperage at driving RPM's.
This alternator uses a smaller 1.75" diameter pulley so a 1/2" or so serpentine belt is required for proper performance and maximum output. Please check our QUICK BELT FINDER for this option.
This alternator is also compatible with our popular MM-VC1 GM 2pin voltage controller!
