Product Description
Mechman Elite Series Billet 400 Amp Alternator – Black Anodized
Fits 1996-2004 Silverado Sierra Tahoe Yukon Escalade and 1998-02 Camaro Firebird
NOT RECOMMENDED FOR SUSTAINED USE ABOVE 5,000RPM
The Mechman Elite Series 400 Amp Alternator delivers serious output and durability, making it an excellent upgrade for high-demand electrical systems. Featuring advanced 6-phase technology, dual massive rectifier assemblies, and 12 oversized diodes, this unit is engineered for reliable performance in daily-driven applications.
These impressive units produce 200+ amps at engine idle and 400+ amps at cruising speed, hot rated. Like most high-output alternators, this unit comes equipped with a smaller 1.75-inch diameter pulley and will typically require a 1/2-inch to 1-inch shorter belt that stock to achieve proper tension in most applications.
Thanks to its simple one-wire design, this alternator is extremely versatile — requiring only a 12V switched source to activate.
Proudly Made In the USA, Mechman alternators are known for their quality, performance, and reliability.
