RECENTLY ADDED FEATURE
We have added an optional W-Terminal or TACH pickup wire to this alternator. This option is only available on these “SE” Denso / dodge alternators that eliminate the PCM. When you select this option we will provide a tach lead for connection to a diesel specific aftermarket tach. This is only available at the time of assembly and older units are not physically eligible for retrofit.
The connection is simple, the wire is provided by us but does not need to be used if no tach is intended.
This will not work with factory equipped tachometers or ignition based tachometers, only a stator signal tachometer. (tach shown is not included)

Perfect fit for 1989 W350 Cummins
Installed easily with no modifications. Taped up the unused tabs and reinstalled the factory battery wire, works perfect. Much better that replacing the external regulator all the time.

Works well, but for almost $400 I should have gotten a sticker to add to my tool box.
Cummins swapped my 1986 K30. This alternator works amazing! Installs just like factory, the wire for the tachometer worked great too. I am unhappy that it cost almost $400 w/ shipping and I didn’t get a sticker for my tool box to add 100hp

Perfect charging solution
I used this on my cummins swapped f250, that had issues with overcharging and then undercharging. After installing this alternator all of my charging issues were gone. Easy to install. Functions great. It is a bit costly but in my situation it was definitely worth the cost

Cummins 1 wire alt
Tried doing the transpo conversion to my factory alt, worked for 6 months until the battery began overcharging and split. Installed the PAperformance unit and have been happy ever since. Also allowed me to hookup my tach simply which is a big plus in a 1st gen truck.
