HE300VG 63mm Turbo Upgrade for 2007.5–2018 6.7L Cummins RAM Trucks

The 6.7L Cummins engine found in 2007.5–2018 RAM trucks has earned a reputation for durability, torque, and long service life. Installed in RAM 2500 and 3500 pickups, as well as 4500 and 5500 chassis cabs, this engine is a favourite among truck owners who tow heavy, work hard, or rack up serious mileage. One of the most impactful upgrades you can make to this platform is replacing the factory turbocharger with a more efficient, reliable unit — and that’s where the HE300VG 63mm turbo comes in.

Designed as a direct upgrade for the factory variable geometry turbo, the 2007.5–2018 6.7 Cummins HE300VG 63mm turbo offers improved airflow, better response, and increased durability while retaining stock-style fitment.

Why Upgrade the Stock 6.7 Cummins Turbo?

From the factory, the 6.7 Cummins uses a VGT turbo to provide quick spool and strong low-end torque. Over time, however, these turbos can suffer from soot buildup, sticking vanes, and reduced efficiency — especially on high-mileage trucks or vehicles used primarily for towing.

In addition, common modifications like tuning, exhaust upgrades, and larger tires can push the stock turbo beyond its ideal operating range. The result is higher exhaust gas temperatures, reduced performance, and increased stress on engine components.

Benefits of the HE300VG 63mm Turbo

The HE300VG 63mm turbo is engineered to address these issues while improving overall performance. It maintains the variable geometry design, which means you keep excellent drivability and towing characteristics, but with a noticeable increase in airflow.

Key advantages include:

• Faster and more consistent spool-up

• Improved mid-range and top-end power

• Lower exhaust gas temperatures under load

• Strong compatibility with mild to moderate tuning

• Drop-in installation with factory-style connections

This makes it an ideal choice for daily-driven trucks, tow rigs, and work vehicles that need dependable power without sacrificing reliability.

Perfect for Work and Towing Applications

Unlike oversized fixed-geometry turbos, the HE300VG 63mm is well suited to real-world use. It delivers usable torque where you need it most, whether you’re hauling a trailer, climbing long grades, or merging onto the highway with a load.

For RAM owners who rely on their trucks to perform every day, this turbo upgrade offers a smart balance between performance gains and long-term dependability.

A Proven Upgrade for the 6.7 Cummins Platform

If you’re running a 2007.5–2018 RAM with the 6.7L Cummins and want to restore lost performance or prepare your truck for future upgrades, the HE300VG 63mm turbo is a solid investment. It enhances efficiency, improves towing confidence, and supports the engine’s strengths without overcomplicating your setup.
