UPGRADE YOUR OEM ALTERNATOR TO GET BETTER IDLE AMERAGE Now you can power all those off-road lights, power tools, big stereo, or all those A/C fans and still keep the battery charged. Our units are designed to provide the highest possible amperage output at idle. This large case Ford 3G alternator is a great high output upgrade for your Ford truck, van, shuttle bus, or Ranger pickup. Our high output alternator will fit the following applications:

Ford E-series vans (buses)   1997 - 2003  4.2 engines

                                              1993 - 1996  5.0 & 5.8 engines

                                              1992 - 2003  7.3 engines
