The 2019–2024 6.7L Cummins (found in fifth-generation Ram 2500 and 3500 heavy-duty trucks) is one of the most capable factory diesels ever built — but towing heavy still pushes the factory Holset HE300VG turbocharger, and its exhaust gas temperatures (EGTs), harder than many owners would like. This guide is the hub for upgrading the turbo on a 2019–2024 truck the right way: what's actually different about these newer trucks, how High Output and Standard Output engines change the equation, how to keep the whole setup road-legal, and where the True North Turbos HE300VG 63mm drop-in fits.

Quick answer: The 2019–2024 6.7 Cummins uses a Holset HE300VG variable-geometry turbo. Owners upgrade it for more airflow, lower EGTs, and faster spool while keeping the factory VGT behaviour and exhaust brake. The cleanest path is a calibrated drop-in like the TNT HE300VG 63mm for 2019–2024, which retains emissions equipment so the truck stays legal.

This guide sits under our broader 6.7 Cummins Turbo Upgrades hub; if your truck is a 2007.5–2018, start with the HE300VG Turbo Upgrade Guide instead.

What's different about the 2019–2024 trucks

These trucks share the HE300VG variable-geometry turbo family with earlier 6.7s, but the calibration, actuator behaviour, and surrounding emissions hardware were updated for the newer platform. If you're coming from an older truck — or cross-shopping a turbo listed for 2007.5–2018 — read 2019–2024 HE300VG: What's Different vs 2007.5–2018 before you buy, so you order the correct fitment.

High Output vs Standard Output — it matters here

The 2019–2024 range splits into two very different engines. The Standard Output (SO) 6.7 Cummins powers Ram 2500s (and base 3500s) with the 68RFE transmission at 370 hp and 850 lb-ft. The High Output (HO) engine is exclusive to the Ram 3500 with the Aisin AS69RC transmission, rated 400 hp / 1,000 lb-ft on 2019–2020 trucks and 420 hp / 1,075 lb-ft on 2021–2024 trucks. Those are different load profiles, and they shape how you should think about a turbo upgrade — see HO vs SO 6.7 Cummins Turbo Upgrade Differences.

Keeping it emissions-legal

Since 2020, EPA and CARB enforcement against emissions-defeat ("delete") tuning has tightened significantly, and Canadian rules differ from the US. The good news: a variable-geometry drop-in that retains the factory DPF, DEF/SCR, and EGR systems lets you add real airflow and towing capability while staying road-legal. We cover exactly how in Emissions-Legal Turbo Upgrades for the 2019–2024 6.7 Cummins.

Keeping the exhaust brake

The factory exhaust brake is one of the best features of these trucks for towing, and losing it is a real concern with some turbo swaps. A VGT drop-in preserves it — the details are in Keeping the Exhaust Brake with a Turbo Upgrade.

The upgrade: TNT HE300VG 63mm drop-in

The TNT HE300VG 63mm for 2019–2024 6.7 Cummins is built around a 63mm 2618 forged milled compressor wheel, retains factory VGT functionality and the exhaust brake, installs as a direct bolt-in, and carries no core charge. Every unit is designed, machined, assembled, and balanced in Canada. For how it compares to other options and who it's for, read Best Turbo Upgrade for a 2019–2024 6.7 Cummins.

Frequently asked questions

Is the 2019–2024 6.7 Cummins turbo different from the 2013–2018 one?

Both are HE300VG variable-geometry turbos, but the 2019–2024 unit uses an updated calibration and actuator setup for the newer platform. Order the turbo listed specifically for your model year — the TNT HE300VG for 2019–2024.

Do HO and SO trucks use the same turbo upgrade?

The TNT HE300VG 63mm covers 2019–2024 6.7 Cummins applications, but HO (Ram 3500/Aisin) and SO (Ram 2500/68RFE) trucks have different power levels and towing demands. See our HO vs SO guide.

Will a turbo upgrade keep my truck road-legal?

Yes, if it retains the factory emissions systems. A VGT drop-in that keeps the DPF, DEF/SCR, and EGR intact is the emissions-legal path — details here.

Does an upgraded turbo keep the exhaust brake?

Yes. A variable-geometry drop-in retains the factory exhaust brake — more here.
