New Holset HE300VG Replacement Turbos for 6.7L Cummins Ram, Commercial ISB and PACCAR PX-7
The Holset HE300VG is the VGT that replaced the HE351VE on the 6.7L Cummins in 2013, and it still runs every current Ram 2500/3500 diesel plus a wide band of commercial ISB trucks and the PACCAR PX-7. Smaller and faster-responding than its predecessor, it uses the same Holset sliding-nozzle design with an updated electronic actuator that has proven more durable than the HE351VE unit it replaced. We stock eight brand new HE300VG configurations covering 2013-2018 Ram trucks (3787604, 3794756), 2019+ Ram (68444771AA), commercial ISB 6.7 builds (2881701, 3794429, 5354525, 5355647RX) and the PACCAR PX-7 (5327342). Each unit is new-built to OEM-spec dimensions with a complete new nozzle mechanism, balanced, and matched to your VIN or engine serial number before shipping. Shops, fleets and distributors order from US stock.

The HE300VG is one of the highest-volume turbo replacements in the diesel world — every 2013+ Cummins Ram carries one, and they fail in a predictable soot-driven pattern. The catch is that one model name hides eight part numbers across two Ram generations and several commercial builds. Getting the right one the first time is the whole game.
We stock the full HE300VG spread: both 2013-2018 Ram units, the 2019+ 68444771AA, four commercial ISB configurations and the PACCAR PX-7 number. Whatever HE300VG truck is in the bay, the part is on the shelf.
Every unit is brand new — new sliding nozzle ring, new actuator interface, new CHRA and housings. The nozzle mechanism is what wears out on these turbos; ours never arrives with someone else's miles on it. No core charge, nothing to return.
The 2019 Ram refresh changed the turbo. A 3787604 does not belong on a 2020 truck, and the 68444771AA does not calibrate on a 2015. We match VIN year and the old turbo's dataplate number on every order, so the generation split never becomes a comeback.
Pickup shops and fleet garages buy from the same inventory: Ram units, medium-duty commercial ISB units and the PX-7 all ship from US stock with the same verification step and the same warranty.
High-volume part, resale-friendly pricing. Shops keep margin, distributors hold steady cost from single units to pallets. Volume terms on the wholesale page.
One-year warranty, US-based support. Before install we run the root-cause check with you — charge piping, oil supply, EGR soot load — because an HE300VG installed over an unresolved soot problem fails on the same schedule as the old one. Details on the warranty page.

WHY CHOOSE US
Confirmed fitment before dispatch, US inventory on the most-replaced VGT in the market, and a team that answers install questions after the sale. One truck or a fleet program, the process is identical. More about our company and quality process.
By year: 2013-2018 trucks run the 3787604/3794756 family; 2019 and newer run the 68444771AA. The two generations use different calibrations and do not interchange. Confirm against the number on your old turbo's dataplate — we verify it again before shipping.
The HE300VG is the smaller, faster successor that took over the 6.7L Cummins in 2013. Same Holset sliding-nozzle architecture as the HE351VE, but with quicker response and a noticeably more durable actuator design. The two are different turbos for different year ranges — 2007.5-2012 trucks take the HE351VE, 2013+ take the HE300VG.
Same turbo family, different part number and calibration. The PX-7 is the PACCAR-badged 6.7L Cummins, and its HE300VG carries the 5327342 number. Order by your engine's part number, and it drops straight in.
Listings state what is included. After installation the actuator must be calibrated — INSITE or the dealer scan tool on Cummins/Ram applications, DAVIE on PACCAR. A healthy existing actuator can usually transfer to the new body and recalibrate.
All units are 100% brand new with a complete new nozzle mechanism — no rebuilt cores, no core charge, nothing to ship back. Balanced, OEM-spec dimensions, one-year warranty.
Yes — this is one of our highest-turnover numbers for fleets and distributors. Consistent wholesale pricing from one unit to pallet quantity, all from US inventory. See the wholesale page.
The HE300VG carries more North American diesel pickups than any other single VGT model, and it also serves a quiet second life in commercial chassis and PACCAR medium-duty trucks. Here is what matters when identifying, diagnosing and replacing one.
| Part number | Application | Notes |
|---|---|---|
| 3787604 / 3794756 | 2013-2018 Ram 2500/3500 6.7L | First-gen HE300VG on pickups |
| 68444771AA | 2019-2022 Ram 2500/3500 6.7L | Updated unit, Mopar number |
| 2881701 | ISB 6.7 heavy-duty commercial | Medium-duty trucks, buses |
| 3794429 | ISB/QSB 6.7 EPA13 | Commercial chassis |
| 5354525 / 5355647RX | ISB 6.7 commercial | Later builds, RX = exchange number |
| 5327342 | PACCAR PX-7 | Kenworth, Peterbilt medium-duty |
Mid-cycle running changes exist — the dataplate on the old turbo always wins over the model year.
When Cummins moved the 6.7 from the HE351VE to the HE300VG in 2013, the goals were faster transient response and a tougher actuator. The nozzle mechanism stayed the proven Holset sliding ring — vanes fixed on a single ring that slides axially — but the actuator drive was reworked, and field experience since has borne it out: HE300VG actuator failure rates run well below the HE351VE era. The exhaust brake still works through the turbo, and that remains the best early-warning system the driver has.
Soot loading is the killer, same as every VGT. The sequence: exhaust brake weakens, boost response slows, then P2262 or P003A sets, then derate. Trucks that idle heavily or run short trips load the nozzle ring fastest. Using the exhaust brake regularly keeps the ring's sliding surfaces clean and measurably delays the failure.
Three steps protect the new unit: find the original failure cause (charge-air leaks, oil condition, EGR soot), install with a flushed feed line and primed turbo, and complete the actuator calibration with a full nozzle sweep before releasing the truck. On 2019+ Rams, confirm the software level supports the 68444771AA — a quick dealer-tool check that prevents a no-calibrate situation.
