The HE400VG is a variable geometry turbocharger released under engine maker number 5459710 for the Cummins fifteen litre block, covering X15, ISX15 and QSX15 applications built from 2016 onward. Unlike a wastegate unit, this charger regulates boost through a commanded vane ring, allowing one hardware family to serve the 400 to 500 horsepower band across multiple calibrations.

| Two Releases On One Truck | 5458936 was superseded by this number, so both appear in the same parts lookups and only one is current. |
| The 5358 Block | Numbers from 5358452 through 5358485 sit beside this one and differ in compressor wheel and housing rather than in flange. |
| Larger Sister | HE500VG is the bigger frame used on the same block at higher ratings, so the two are confused by size rather than by number. |
| Three Engine Names | X15, ISX15 and QSX15 describe the same fifteen litre block in road, industrial and older naming, and the installation decides the release. |
Actuator Not Included: Several sellers quote the charger without the electronic actuator and say so only in the body text, which leaves a unit that cannot be commissioned.
Deposit Is Not Discount: Remanufactured supply carries a refundable deposit in the hundreds of dollars with a thirty day return window, and the invoice reads lower than the cost until the core goes back.
One Number, Many Ratings: Four hundred to five hundred horsepower is covered by this charger family, so the rating has to be matched from the engine plate rather than from the model name.
Vane Sticking Reads As A Sensor: A restricted vane ring produces fault codes that point at the actuator or the boost sensor, and replacing either leaves the deposit spent and the fault present.
Oil And Soot Source: A charger changed onto an engine with a blocked breather or a leaking injector will coke its ring within a season, so the upstream cause is checked first.

Frame size, and therefore how much air the unit can move at the top of its range. The larger frame serves the higher ratings on the same fifteen litre engine, and the two are often mixed up because the housings look similar in a photograph. A charger from the wrong frame will bolt up and will miss its boost target at one end of the range.
In the deposit, which is refundable only when the old unit comes back inside the agreed window. A quotation that looks several hundred dollars cheaper than a new unit is usually resting on that deposit and on the assumption that the core is returned in a reusable state. Cracked housings or a bent shaft turn the deposit into a charge.
Because the vane ring is commanded by the engine controller, so the same hardware can be driven to different air flows by different calibrations. That is convenient for a manufacturer and awkward for a buyer, since the physical part looks identical across the band and only the plate confirms which release the engine left with.
The fifteen litre block sold as X15, ISX15 and QSX15.
