This is the Alliant Power AP90043, an HE300VG variable geometry turbocharger remanufactured by Alliant Power. Alliant Power lists it for the Cummins ISB 6.7L at the EPA 2017 emissions level (EPA17). It replaces Cummins turbocharger kit 6411490, which took over from 5604188, and Cummins 5605001, 5604945, 5354552 and 5354495. It is the turbo only: the electronic actuator is not included. A refundable core applies.
A turbo without the actuator makes sense when the turbo itself has failed (shaft play, oil in the charge pipes, a seized vane ring) and the actuator still tests good. The same turbo with the actuator fitted is Alliant Power AP90943, which uses actuator AP91004 (Cummins 6382091). Whichever actuator you fit has to be calibrated to the turbo with the engine maker’s service software, so plan for that. The ISB 6.7L has used several HE300VG turbos that carry different Cummins numbers, so match the number on your old turbo before you order. Ram trucks carry their own turbo numbers.
Confirm Fitment Before You Order
ISB 6.7L HE300VG turbos carry different Cummins numbers from one engine build to the next, and this one comes without the actuator. Ram trucks carry other turbo numbers (2019 to 2024: Alliant Power AP90049). Have your engine serial number and the Cummins or Holset number from the data plate on your old turbo ready. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.

- HE300VG variable geometry turbo, actuator not included
- Replaces Cummins 6411490, 5604188, 5605001, 5604945, 5604168, 5354552, 5354495 and 5354476

The actuator is not included. Whichever actuator you fit has to be calibrated to this turbo with the engine maker’s service software. Find out why the old turbo failed before you fit this one: check the oil feed and drain, the intake and charge pipes for debris, and soot build-up on the exhaust side. Use new gaskets and prime the turbo with clean oil before the first start.

Frequently Asked Questions
Does the AP90043 come with the actuator?
No. AP90043 is the turbo only. The same turbo with the actuator fitted is Alliant Power AP90943, which uses actuator AP91004 (Cummins 6382091).
What numbers does the AP90043 replace?
It replaces Cummins turbocharger kit 6411490 and Cummins 5604188, 5605001, 5604945, 5354552 and 5354495, and the RX remanufactured versions 6411490RX and 5604188RX. It also crosses to Holset 6395599.
Will the AP90043 fit my Ram 2500 or 3500 pickup?
It is listed by Cummins part number for the ISB 6.7L, not for Ram pickups. Ram trucks carry their own turbo numbers (2019 to 2024: Alliant Power AP90049), so call 530-668-0818 with your VIN for those.
Do I need to calibrate the actuator after fitting the AP90043?
Yes. An actuator fitted to this turbo has to be calibrated to it with the engine maker’s service software.
