This kit comes with everything you need for a clean, reliable installation on your Ram 2500
Looking to upgrade the turbo on your 6.7L Cummins for better performance, durability, and faster spool than the stock VGT unit? The Smeding Diesel S300 Turbo Kit is engineered to do just that, replacing the factory HE300V / HE351VE turbo with a robust fixed-geometry S300 turbo that delivers improved airflow, increased responsiveness, and long-term reliability.
This kit comes with everything you need for a clean, reliable installation on your Ram 2500 or 3500, including:
- S300 turbocharger on a divided T4 exhaust manifold
- T4 inlet flange to bolt to the exhaust manifold
- Gaskets and mounting bolts
- Coolant block-off plugs
- Oil drain extension and turbo drain gasket
Unlike the factory VGT turbos, the S300’s fixed-geometry design has no vanes or actuators to fail, making it a stronger solution under sustained boost and high shaft speeds. The kit retains your factory air intake, downpipe, and intercooler piping, so installation stays straightforward and cost-effective.
Performance & Options
This turbo kit offers multiple compressor wheel choices to suit different performance goals:
- Cast 62mm & Cast 66mm: reliable, cost-effective upgrades
- Billet SXE options (63mm, 64.5mm, 66mm, 69mm, 72mm SXE-R, 63mm SXE-R): higher airflow and horsepower potential
- Thrust bearing choices: standard, heavy duty, or extreme duty steel 360° bearings for added durability under load
Billet wheels and stronger bearings unlock more horsepower potential (in many cases up to 650+ HP in the right setup), while cast options offer a solid balance of spool and reliability.
Why Choose the S300 Turbo Kit
- Eliminates common VGT failures (vanes, actuators, corrosion)
- Faster spool and increased horsepower potential over stock
- Retains factory components for easier installation
- Builds turbo strength and protects engine components with lower drive pressure and reduced EGT
- Multiple size and bearing options to match your goals
Whether your goal is improved daily performance, stronger heavy-haul capability, or a more durable platform for future mods, the Smeding Diesel S300 Turbo Kit gives you a beefier turbo solution without the complexity and failure points of the variable geometry system.
