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.)

With performance engines pushing redlines up higher and higher, alternators are being forced beyond their design. Holley's premium alternators can tolerate 30 percent higher rpms than conventional models. The attention to cosmetic detail on these units is above and beyond what you would expect, too. The entire outside housing has been sculpted for a smooth silhouette that hides the ugly details we typically think of as alternators. If you drag race, autocross, or just hot rod your ride, be assured that Holley premium alternators won't fly apart on you. Features: * Available in natural, black, and polished finishes * Works with all Holley accessory brackets, as well as 4th generation F-body, most 1998 thru 2004 GM trucks, and many other applications * 150 amp output * Smaller and lighter than Holley high-amp alternators * Housings are smoothed to make polishing clean (no buffer cut marks trying to get in tight corners) * Rear cover is aluminum instead of typical black plastic * Ideal when size and clearance matter * Black and polished pulley covers are available on models that don't already include them * Designed for use with Holley alternator weatherproof pigtails (not included)

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 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.

Standard Motor alternator rectifiers are available for thousands of vehicle applications. These units in your assembly convert the AC (alternating current) that alternators produce into DC (direct current) for use by the vehicle's battery and electrical system. Harsh power demands on the rectifier can cause alternator diodes to fail. At that point, you may notice frequent engine stalls or dimming lights. Often you can simply replace the rectifier, not the entire alternator. Order the model designed for your specific vehicle application.
