Recipe - Cummins 6.7L ISB Diesel (Ram HD, 2019+ generation)
Specific Fix build
Reliability tier: aggregated - verify before ordering, see /disclosure/
HE300VG VGT turbo repair for 2019+ Ram HD (mode VGT turbo electronic actuator failure (HE300VG family)): the vaned nozzle ring sticks from soot/carbon and the actuator loses position control - limp modes, boost codes, whine. Diagnosis must separate an actuator/vane-control fault from a worn CHRA. The verified OEM listing covers the complete turbo assembly; a standalone actuator listing is still a data gap and is not forced here.
Parts
- 6.7L Cummins VGT Turbocharger, 2019+ (OEM Mopar) - OEM HE300VG turbo assembly 68444771AB - the verified replacement (qty 1)
- 6.7L Cummins Turbocharger Actuator (Mopar 68444773AB, 2019+ HE300VG family) - if diagnosis points at the actuator alone, an actuator-only repair is the cheaper path - no verified OEM listing as of 2026-09-28 (honest gap) (qty 1)
Install order
- confirm the failure mode: stuck vanes (soot) vs actuator electronics vs CHRA wear - boost log + actuator sweep test
- try a desoot/cleaning pass first where the truck allows it; many sticking-vane cases clear before any part is ordered
- replace the assembly (or the actuator alone if the gap gets filled and diagnosis supports it)
- verify boost/control after the swap; check for oil-side root causes (CCV/pressure imbalance)
Expected outcome
Boost and VGT position control back to spec; no limp events under load.
Do not
- do not buy an actuator-only 'fix' sight-unseen - wrong-actuator returns are the common money pit here
Parts budget
About $1,450-$6,850 in parts. It depends on what the diagnosis finds; each option below is what you buy together. Prices marked "at Dave's" are Dave's Auto Center's, the same as in his store; the others are approximate prices from OEM and maker catalogs, rounded (a manufacturer's list price can run higher). Parts only, no labor.
DIY or shop: Shop: turbo replacement on a 2019+ HD is an engine-bay-out-or-heavy-access job.
