This is the Holset 3798402HX, an HE300VG variable geometry turbocharger for the Cummins ISL 8.9L with EPA 2013 emissions. Catalogs also list it for the ISC, and some call this turbo the HE351VE. It is remanufactured by Holset, the Cummins turbo division, not by a third party. It replaces Cummins 3798351 and Holset 5326678, 5326681 and 5326684, and it is the remanufactured twin of the new Holset 3798402H. A refundable core applies.

This is the short turbo: it comes without the electronic actuator. You move your own actuator over or fit a replacement. Catalogs list the Holset 6382091 actuator kit, the 12 volt kit, for this turbo. The 8.9L ISL used more than one variable geometry turbo over the years, and a second HE300VG is listed for it under different Cummins numbers, so match the number on your turbo data plate and your engine serial number before you order. Low boost, a sticking vane fault, oil in the charge pipes or shaft play are the usual reasons these get replaced.
