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. Order the model recommended for your auto application.

MechMan Elite Series cast alternators offer great output at idle RPM and excellent durability in a direct bolt-in package. Their 6-phase technology, combined with massive twin rectifier assemblies and 12 diodes, makes these alternators totally durable for daily use, while still maintaining great output at low-rpm. These alternators will make 180 amps at engine idle speeds—with a full 250 amp output at cruising speeds. The units come with an OEM diameter pulley, making them perfect for high-rpm and racing use. They're available for fitment on a wide range of cars, trucks, and vans from the 1990s and up. Order the model recommended for your application. (Note: Elite Series cast alternators may require a rectangle to oval adapter harness if your vehicle was equipped with the CS144 heavy-duty charging option from the factory. This is not common.)

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.

Flaming River billet HD amp high-output alternators are better than OEM. With new technologies and increased efficiencies, they offer excellent output at extremely low engine rpm, more horsepower to the wheels, and less energy wasted in the form of heat. These units are built with precision-balanced low-mass rotors that offer high-rpm capability and excellent output at speeds as low as 400 rpm—so that you gain a broader operating rpm range and more flexibility in the size of the crankshaft pulley you can choose. Their twin rectifier plates offer twice as many diodes to provide tremendously more surface area to dissipate heat better. Plus, they're available in a choice of finishes to keep your engine bay looking good, too. Less heat, more power—Flaming River billet HD amp high output alternators can help you solve premature failure, intermittent electrical accessory problems, or low voltage at any engine rpm. Dozens of models are available; order the replacement alternator designed for your vehicle application.
