Mechman Alternators Alternator, E-Series Billet, 370 amp, 12V, 1-Wire, 6 Rib Serpentine Pulley, Black Anodize, GM Fullsize Truck 2007-08, Each (B8302370B)

Most powerful alternator i have found. If you have charging issues. Battery voltage dropping everytime you come to a stoplight. Lights dimming. Fans slowing down stereo stops hitting hard. Engine starts running rough. then you need this alternator this 6 phase beast charges 200 amps at idle and 370 at hwy speeds and runs cooler than my previous 130 amp alternator. Voltage never dips. Rock solid 14.6 constantly. Beware you must add a 4/0 ground. And 4/0 power wire from alternator to the battery and a 4/0 ground one from engine to the frame and body big 3. Or this will make enough power to melt wires 4gage and smaller. This is the real deal. Not a swap meet or made in china product with inflated peak numbers that would only be achieved in A few milliseconds. this looks awesome and puts out. Must have item to solve charging issues.

it works,,hope it lasts the return period..

I have a lot of consumers in my van. Thermoking unit( 5 fans), 2 fans for a/c, 2 fans for engine cooling, 1 fan for transmission cooling, 2 fans for a/c in cabin, inverter 110v with full size freezer, and when I use OEM GM alternator (120A) in idling voltage dropped to 11.3V. Long time I tried to fix it, but it was just only one right way for working properly: THIS Incredible MONSTER !!!!! Thank you guys, thank you for produce it, thank you Micheman!
