S-Series 240 Amp Alternator

The Mechman S-Series 240 Amp alternator (model 8165240B) is engineered for 1988-1995 GM trucks, offering a significant upgrade in charging capacity. This high-output unit features a 6-phase design, which provides exceptional performance at low RPMs while consuming less horsepower than traditional 3-phase alternators. Its robust construction includes 12 diodes, twin rectifier plates, and superior airflow, ensuring greater durability and reliability even under demanding conditions, outperforming standard Delco CS130-based alternators. Designed as a direct replacement for standard CS130 "left mount" alternators commonly found in 1987-1995 Chevy C1500 Pickups and some aftermarket setups, this alternator features a custom housing. The seamless rear cover with a side output plug enhances clearance between the alternator and the engine, contributing to a cleaner appearance. Installation is simplified with a single-wire hookup to an ignition-switched 12V+ source, allowing the alternator to operate in sync with the ignition. For optimal performance, a properly sized positive and ground cable should be run directly from the alternator to the battery terminals, ensuring proper functionality regardless of the existing wiring harness. With a 240 Amp output and 12-volt compatibility, this alternator is well-suited for vehicles with high electrical demands. It comes equipped with a serpentine style pulley and an internal regulator, streamlining the installation process. Its compact size and standard GM mounting ears also make it a viable option for various aftermarket and custom bracket installations, providing a versatile solution for upgrading your vehicle's charging system.
