HE300VG Turbo & Exhaust Manifold Package for 6.7 Cummins | 2007.5–2018 Ram 2500/3500
This Diesel Power Source® turbo and manifold package combines the two most common 6.7 Cummins replacement components into one complete kit for 2007.5–2018 Ram 2500 and 3500 trucks. This is a direct factory VGT replacement that keeps your truck running the OEM-style variable geometry turbo platform with full exhaust brake, warm-up, and emissions compatibility. The package includes a DPS HE300VG VGT turbocharger with brand-new pre-calibrated actuator, the DPS T4i 2-piece high-flow exhaust manifold, a multi-layer turbo and manifold gasket kit, and a spin lock bolt kit with studs and nuts. Everything you need for a complete turbo and manifold replacement in one box.
Three turbo sizes are available to match your power goals. All three options maintain factory VGT function, exhaust brake, warm-up features, and emissions compatibility while delivering improved airflow, faster spool-up, and lower EGTs compared to the factory turbo and manifold.
Looking for an aftermarket performance turbo instead of a factory-style VGT? Diesel Power Source® also offers the 3rd Gen Swap Kit with an S300 turbo and the Add-a-Turbo compound kit for trucks that need more airflow, lower EGTs, or higher horsepower than the factory VGT platform can support.
Why Replace the Turbo and Manifold Together?
On the 6.7 Cummins, turbo failures and manifold failures are closely related. A cracked or warped manifold causes exhaust leaks that reduce the exhaust energy reaching the turbocharger, forcing the turbo to work harder to maintain boost. This accelerates bearing wear, actuator fatigue, and vane sticking. Meanwhile, a failing turbo that can't maintain proper boost creates higher EGTs and increased backpressure, which accelerates manifold cracking.
Replacing only one component often leads to a second failure shortly after, along with the labor cost of going back into the same job. This package solves both problems at once with fresh sealing surfaces, new MLS gaskets, new studs, and matched components that are designed to work together. It also saves labor compared to doing two separate jobs on the same truck.
What's Included
- DPS HE300VG Turbocharger — Brand-new pre-calibrated electronic actuator (not remanufactured), forged milled compressor wheel (63mm and 66mm options), VSR high-speed balanced, no core charge
- DPS T4i 2-Piece Exhaust Manifold — High-silicon ductile iron, 2-piece expansion joint design, 62% flow increase over stock, pre-drilled pyrometer ports, fully EGR compatible
- Multi-Layer Turbo & Manifold Gasket Kit — MLS gaskets for both the manifold-to-head and turbo-to-manifold connections
- Spin Lock Bolt Kit — Serrated flange bolts, studs, and nuts for secure manifold installation
Important: Speed sensor is not included with the turbo. Transfer the speed sensor from your original turbocharger during installation.
Turbo Size Options
| Turbo Option | Compressor | Max HP (Rear Wheels) | Best For |
|---|---|---|---|
| HE300VG (Stock) | Stock compressor & turbine | ~400 HP | Stock replacement, daily driving, mild tuning |
| HE363VG (63mm FMW) | 63mm forged milled wheel | ~550 HP | Moderate tuning, towing, 12% more power than stock |
| HE366VG (66mm FMW) | 66mm forged milled wheel | ~700 HP | Performance builds, aggressive tuning, 15–16% more power |
Tuning note: The stock-size HE300VG requires no tuning. The 63mm and 66mm options benefit from tuning and supporting modifications to take full advantage of the increased airflow.
Fitment
This package fits 2007.5–2018 Ram 2500 and 3500 pickup trucks with the 6.7L Cummins engine and factory HE351VE or HE300VG turbocharger (T4i flange). Select your exact model year at checkout so DPS can configure the correct turbo and actuator for your truck.
Does NOT fit 2013–2018 Cab & Chassis models (Ram 3500/4500/5500). These trucks use a different manifold configuration and turbo orientation.
Does NOT fit 2019+ Ram trucks. The 5th gen uses a different manifold and turbo configuration. See: 5th Gen HE300VG Turbo & Manifold Kit (2019–2024)

Only Need the Turbo?
If your manifold is still in good condition and you only need the turbocharger, see the standalone turbo listing:
DPS HE300VG Replacement Turbo for 6.7 Cummins (2007.5–2024)
Only Need the Manifold?
If your turbo is still functioning and you only need the exhaust manifold, see the standalone manifold listing:

Want Even More Power?
If your horsepower goals go beyond what the factory VGT platform can deliver, consider upgrading to a compound turbo system. DPS compound kits add a large atmospheric turbo to your VGT for 200–300°F cooler EGTs and significantly more airflow:

A cracked manifold reduces the exhaust energy reaching the turbocharger, which accelerates turbo wear. A failing turbo creates higher EGTs and backpressure that accelerate manifold cracking. Replacing both components together breaks this cycle, gives you fresh sealing surfaces with new MLS gaskets and studs, and saves labor compared to doing two separate jobs. This package includes everything needed for a complete turbo and manifold replacement in one box.
For the stock-size HE300VG turbo, no tuning is required. The turbo is a direct-fit replacement with a pre-calibrated actuator that works with factory emissions equipment and exhaust brake. If you choose the 63mm or 66mm turbo option, tuning and supporting modifications are recommended to realize the full airflow and power potential.
All three options bolt into the factory location and maintain full VGT function. The stock HE300VG supports approximately 400 rear-wheel HP. The 63mm (HE363VG) uses a larger forged milled compressor and turbine wheel for approximately 12% more power, supporting up to 550 HP. The 66mm (HE366VG) increases power by 15–16% and supports up to 700 HP with proper tuning and supporting modifications.
No. This package fits 2007.5–2018 Ram 2500 and 3500 pickup models only. The 2013–2018 Cab & Chassis trucks (Ram 3500/4500/5500) use a different manifold configuration and turbo orientation. For 2019–2024 Ram trucks, see the 5th Gen Turbo & Manifold Kit.
Common signs include: turbo whistle or howl, black smoke on acceleration, turbo lag or slow throttle response, VGT actuator or position fault codes, weak or inoperative exhaust brake, visible cracks or soot marks around the manifold flanges, and ticking or hissing sounds at cold start that fade as the engine warms. If you're seeing multiple symptoms, replacing both the turbo and manifold together is typically the most reliable and cost-effective repair.
This package includes the multi-layer turbo and manifold gasket kit and the spin lock bolt kit with studs and nuts, which are sold separately when purchasing the turbo and manifold individually. You get matched components configured for your specific model year, all in one shipment, ready to install as a complete job.

DROP IN & DONE
Ram 3500 Dually 475k miles and counting. Ive been workin on trucks for 20+ years and this was hands down one of the easiest installs. Threw this HE300VG turbo and manifold package on my 2012 Ram 6.7 and she bolted up slick. No mods no BS. Dropped it in, torqued it down, it fired right up. The spool up is way quicker than stock, and Im pullin my loaded flatbed through the Rockies with no problem. Props to Diesel Power Source for making it easy for us working guys.
