DC power is the best in aftermarket alternators. This alternator is the 190 amp version (140amps at engine idle). I bought this last month and spent 434$ on the alternator and the wiring. It has never been installed (it has just been sitting in my living room). I also bought the adapters to connect 0 gauge wiring to the battery (these were 23$ each)
I am looking to sell this stuff because I'm getting out of the ranger scene. My loss is your gain.
Check out the website at www.dcpowerinc.com
for details on the alternator. Here are the photos. I am asking 300$ plus actual shipping for everything shown.
