This is the Alliant Power AP90049, a Holset HE300VG variable geometry turbocharger remanufactured by Alliant Power for the Ram 6.7L Cummins. Catalogs list it for 2019 to 2024 Ram 2500 and 3500 trucks and for 2019 to 2022 Ram 4500 and 5500 cab and chassis trucks. It replaces Cummins turbo number 5640906 and is listed against Mopar 68444771AA. It is a short turbo, which means the electronic actuator is not on it: Holset sells the complete turbo with actuator as 5554227H new and 5554227HX remanufactured. You move your own actuator over, or fit a replacement, and calibrate it to the turbo.
A short turbo is the right choice when the turbo itself has failed (shaft play, oil in the intake, a damaged wheel, a nozzle ring stuck with soot) and the actuator still tests good. If the truck has an actuator fault as well, Alliant Power AP90949 is this same turbo supplied with the actuator. The actuator for this turbo is Alliant Power AP63587, the Holset 6382096 type, and it has to be calibrated to the turbo with a scan tool once it is bolted on.
Confirm Fitment Before You Order
This number is for the 2019 and later Ram 6.7L Cummins. The 2013 to 2018 Ram and the 2007.5 to 2012 Ram take other turbos, and Cummins ISB 6.7L engines in medium-duty trucks take other numbers again. For a 2023 or 2024 Ram 4500 or 5500, send us the VIN first: the catalogs do not agree past 2022 on those two models. Tell us if you need the actuator too. Call 530-668-0818 and we will confirm the exact match at no charge before anything ships.

Fits / Applications
- 2019 to 2024 Ram 2500 and 3500, 6.7L Cummins
- 2019 to 2022 Ram 4500 and 5500 cab and chassis, 6.7L Cummins
- Short turbo: move your actuator over, or add actuator AP63587
- Supplied with the actuator, the same turbo is AP90949
The actuator is not included. When you move your actuator over or fit a replacement, it has to be calibrated to the turbo with a scan tool before the truck goes back to work. Fit new gaskets, check the oil feed and drain for restriction, and find out why the old turbo failed (oil supply, soot, a foreign object) before the new one goes on.

Frequently Asked Questions
Does the AP90049 come with the actuator?
No. It is a short turbo, sold without the electronic actuator. If you need the actuator as well, the same turbo supplied with it is Alliant Power AP90949, and the actuator on its own is AP63587.
Will the AP90049 fit my 2018 Ram 6.7L Cummins?
No. This number is for 2019 and later trucks, and the 2013 to 2018 Ram takes a different HE300VG turbo. Call 530-668-0818 with your VIN and we will match it.
Does the AP90049 fit Ram 4500 and 5500 cab and chassis trucks?
Yes for 2019 to 2022 trucks, which two catalogs list alongside the 2019 to 2024 Ram 2500 and 3500. For a 2023 or 2024 Ram 4500 or 5500, call 530-668-0818 with the VIN before you order.
What numbers does the AP90049 replace, and is there a core?
It replaces Cummins 5640906 and is listed against Mopar 68444771AA and the Holset complete turbo 5554227H. It is remanufactured by Alliant Power. A refundable core applies, and it comes back when we receive your old turbo.
