The Smeding Diesel S300 Turbo Kit is a complete performance upgrade designed for Duramax 6.6L trucks. This kit allows you to install a high-flow S300 frame turbocharger on your Duramax using most of the factory components, providing a direct bolt-in solution that improves airflow, reduces boost restrictions, and unlocks significant power potential when paired with proper tuning.

Unlike restrictive stock VGT turbos that can choke airflow and generate high drive pressure, the S300 kit delivers better exhaust flow and lower drive pressure for stronger performance and healthier engine operation. Whether you’re building a tow rig, daily driver, or high-performance truck, this kit provides an excellent balance of power, reliability, and value.

FEATURES & BENEFITS:

  • High-Flow S300 Turbocharger: Offers improved airflow over the factory VGT turbo, helping to increase horsepower potential and reduce backpressure. 
  • Direct Bolt-On Design: Works with the factory intake, intercooler pipe, and up-pipes in most setups for a straightforward installation.
  • Complete Hardware Kit: Includes T4 pedestal, downpipe, oil feed and drain lines, coolant plug, gaskets, and necessary mounting hardware for a full installation. 
  • Cost-Effective Upgrade: Offers a high-performance alternative to expensive VGT replacement turbos while delivering better exhaust flow characteristics. 
  • Versatile Power Options: Available with multiple turbo sizing choices, allowing builders to tailor power potential for towing, hauling, or performance. 

KIT CONTENTS:

  • Smeding Diesel S300 Turbocharger
  • T4 Turbo Pedestal
  • 3.5″ Downpipe (Fits factory or aftermarket exhaust)
  • Oil Feed Line
  • Oil Drain Line
  • Coolant Plug
  • Gaskets & Miscellaneous Hardware

This S300 Turbo Kit provides a solid foundation for increased power and performance on your Duramax 6.6L, with a robust design and quality components that make installation and future tuning upgrades easier and more effective.

Not for narrow feet, very lightweight.
Size: 7.5, Color: Black
My feet are slightly narrow; these were not adjustable enough to make secure. Otherwise they are cute. The material feels kind of light, these were my first attempt at UGGs so I'm not sure if that's typical or an actual quality issue. Either way, they don't seem very durable but I can't imagine these are meant for roughing it.

Nice so far.
Size: 6.5, Color: Molasses
Comfy. They were tight the first day across the toes but as I've worn them a couple times they are loosening up. The sole is forming to my foot. These are very much like Doc Martin's from the early 2000s. Not sure about quality since I haven't had them for very long.
