Mechman high output alternators · Authorized dealer
A Cobalt makes an easy project car: inexpensive to buy, simple to work on, and ready for gauges, LED lighting and a trunk full of subwoofers. This Chevrolet Cobalt high output alternator collection lists two Mechman units, 240 Amp and 320 Amp, for the 2.2L Ecotec in 2005-2010 models and the 2.4L in 2005-2009 models.
Cobalt builds usually grow in stages. First comes a new head unit, then an amplifier and subwoofer, then a gauge pod, interior LEDs and brighter lighting. Each step adds load, and the original alternator on a high-mileage compact was never meant to carry it all. Voltage that sags under bass or at idle shows up as dimming lights and an amplifier that cuts out. A Chevrolet Cobalt high output alternator gives the build a stable base before the next upgrade goes in.
The 240 Amp unit suits a first system with one amplifier and some lighting. The 320 Amp unit is the choice for multiple amplifiers or a competition-minded setup. Supercharged models are not part of this listing, so enter your year and engine in the vehicle finder above the products to confirm fitment.
These Mechman high output alternators come from the GM Ecotec series shared with the Cobalt's Pontiac sibling, the Pontiac G5, and with the Chevrolet HHR. Plan for heavier power and ground cable from our amp wiring kits, and see the full Chevy range on the Chevrolet alternators page.
