150 Amp High Output GM CS144 Large Case Alternator

This is anew 150 Amp Alternator. We use GM's style workhorse, the CS-144 series alternator, and build it to our specifications to provide you with the best output for your needs. (Also see our store listing for our 200, 250, and 300 amp versions) We build these units to provide 115 amps at an idle. That's as much as the original units put out at high RPM. It will plug in to most OEM wiring harnesses for GM vehicles from 1992-2000.

Our high outputalternator can also be used to upgrade most original externally and internally regulated alternators from 1963 through 2002 year models. This unit is great for applications requiring additional charging capacity such as auxiliary batteries, stereo systems, off-road lighting, etc. For the 1-Wire version see our listing in our eCRATER store.
