Every Diesel Power Source® turbo for the 6.7 Cummins is on this page. Whether you are replacing a worn factory VGT, chasing lower EGTs and stronger towing, or building a high-horsepower truck, the options below cover 2007.5-2024 Ram 2500 and 3500 trucks. DPS turbos are built on the HE-series, S300, and S400 platforms and matched to your model year and power goal.
Which 6.7 Cummins Turbo Is Right for You?
Replace a Failing Factory Turbo
The HE300VG replacement restores spool, exhaust brake, and drivability in the factory location. The 60mm size covers stock to 400 RWHP.
More Power, Factory Fitment
The HE363VG covers stock to 550 RWHP and the HE366VG covers 425-650 RWHP, both with the factory exhaust brake. Past that, the T4i S300 Turbonator® VGT runs from about 450 to 900 RWHP across its three sizes.
Keep the Factory Turbo
An Add-A-Turbo kit uses the factory turbo as the high-pressure turbo and adds a large atmospheric turbo, with a path to a full compound kit later.
Maximum Power
A full compound kit gives the largest EGT reduction and power improvement in the DPS lineup. Above about 600-650 HP, compounds are typically the way to keep street manners and towing.
HP figures are approximate rear wheel horsepower and vary with tuning, fueling, and supporting modifications. Not sure which fits? Use the Turbo Selector or call 801-930-8404.

Stuck Turbo Syndrome
The factory VGT controls boost with movable vanes driven by an electronic actuator. Carbon buildup, actuator wear, and oil coking make the vanes stick. Signs include lost power or limp mode, sluggish spool, a weak exhaust brake, and codes such as P003A, P2262, P226C, P00AF, and P0299.
Replace the Turbo and Actuator Together
Sticking vanes overload the actuator, and a weak actuator lets the vanes load up with carbon. Every DPS HE300VG replacement ships with a new pre-calibrated actuator, so no calibration is needed after installation.
One Turbo for 2007.5-2024
DPS supplies the HE300VG to replace both the HE351VE (2007.5-2012) and the HE300VG (2013-2024). Select your model year at checkout and DPS configures the correct turbo and actuator.
Larger Wheels Run Cooler
Each 1mm of compressor wheel adds roughly 10 RWHP and lowers EGTs. The 63mm and 66mm sizes typically last longer than the factory size because they run with more headroom.

Fitment
- 2007.5-2012 Ram 2500/3500 6.7L Cummins (factory HE351VE)

- Running an aftermarket intercooler? Tell DPS when you order.
Good to Know
- The stock 6.7L turbo supports approximately 420 RWHP before it limits power.
- Expect about 13.5 HP per PSI of boost on a 6.7L. Head studs are recommended above 48 PSI on 2007.5-2018 engines.
- HE-series turbos use the factory coolant lines to cool the actuator electronics. DPS S300 turbos are oil cooled.
- Full compound kits and 3rd Gen Swap kits replace the factory turbo and are for trucks that have already been deleted.
- Tuning is the owner's responsibility. DPS does not sell tuners or tuning.
- Warranty under the Diesel Power Source® PMA: HE300 series 2 years / 24,000 miles; S300 and S400 turbos 1 year / 15,000 miles, whichever comes first. Registration within 14 days of purchase is required.
