The MechMan S Series of 6-phase billet racing alternators offers incredible output in a compact and durable package. Highly efficient, these units use less horsepower per kW than conventional 3-phase alternators. They feature 12 diodes, twin rectifier plates, and outstanding airflow to ensure long service life, even in severe conditions. The alternators are available for a broad range of domestic and import applications in 170 or 240 amp configurations—as well as a variety of finishes. (The 170 amp S Series unit uses a stock diameter pulley, making it perfect for high-rpm and racing use.)

MechMan S Series 6-phase alternators offer incredible output in a compact and durable package. The 240 amp models offer the best balance between peak output, and output at engine idle RPM; while the 320 amp models are all about max power and not designed to charge at low idle speeds. Both S Series alternators feature 12 diodes, twin rectifier plates, and outstanding airflow ensure long service life, even in severe conditions. These units come equipped with a smaller 1.75 in. diameter alternator pulley, and will require a slightly shorter drive belt to be installed for proper belt tension.

MechMan 6-phase hairpin high-output alternators offer a solution to the inadequate alternators that come from the factory on specified vehicles. These replacement units feature twin rectifiers with 12 massive press-fit diodes, as compared to the small 8-diode rectifier in the stock alternator. Even mild performance builds will typically consume more amperage than what stock alternators can provide. Hairpin stator technology provides better high-rpm durability and better resistance to heat from the turbo manifold. The alternators utilize a high rpm-friendly larger diameter pulley, and bolt directly in place of the original equipment. Select the high-output racing alternator model recommended for your application. Note: A 4-gauge or larger positive and negative cable needs to be run between the alternator and the battery terminals for proper function.

MechMan adjustable external voltage regulators include a 2-pin alternator harness. These combos work with most OEM and MechMan Chrysler units from 1999-2006, and will allow the user to adjust charging voltage anywhere from 13.8 to 19.0 V. Please note: Installation of this unit will leave the OEM alternator harness unplugged, which will result in the check battery light in the dash staying on all the time. Compare the plug on your alternator to verify compatibility.

MechMan indicator light module connectors are for use on GM vehicles with MechMan alternators and equipped with a 2-pin regulator and a RVC (Regulated Voltage Control) sensor. Simply plug module into your vehicle's factory harness and tie out of the way. This will eliminate the check charging system code (battery light). These are especially popular for the customer who wants to bypass the RVC system so that they can run a stand-alone alternator. The reason for this is that when run in the factory form on these model vehicles there will be fluctuating voltage and normally, they will charge at a lower voltage. Although this is all normal since the PCM is controlling the voltage in order to acquire max fuel economy, some will opt to go with a standalone unit to acquire a higher and more stable voltage.

MechMan High-Output 6-Phase alternators offers incredible low-rpm output in a compact and durable package. Highly efficient, these units use less horsepower than conventional 3-phase alternators. Their 12 diodes, twin rectifier plates, and outstanding airflow ensure much better durability than standard Delco CS130-based alternators, even in severe conditions. This custom designed housing directly replaces standard CS130 "left mount" alternators as used on 1987-95 Chevy C1500 pickups and some aftermarket accessory drives. A side output stud and seamless rear cover with a side output plug allow for better clearance from the back of the alternator to the front of the engine and a smooth appearance. A single wire on the provided pigtail gets connected to any ignition-switched 12+ volt source to turn the alternator on and off with the ignition switch. Simply run a properly sized positive and ground cable from the alternator to the terminals of the battery and the alternator will work perfectly, regardless of what kind of wiring harness you have. Because of their compact size and standard GM mounting ears, these alternators also work well in many aftermarket or custom bracket installations. Order the model recommended for your car, truck, or van application.
