Fitment:
This is a direct fit high-output alternator for the 1967-1978 GMC P35 4.8L. Being a direct fit, this alternator fits directly into your stock alternator location.
Plug:
This high-output alternator comes with a separate adaptor plug. One side will plug directly into the aftermarket high-output alternator, and the other side will plug into the factory plug.
NOTE: If you require charging at a certain voltage setpoint, we offer a selection of different voltage regulators that you will need to purchase with the alternator for it to be installed. View our Regulator Options Here.
Pulley:
This alternator also comes with a smaller pulley, which causes it to spin faster than a larger pulley. This can help the alternator produce its maximum output. With a smaller pulley, it is required to install a 1/2" - 1" shorter belt.
See this Blog Article for assistance in finding the correct shorter belt.
