Duramax T4 S300/S400 Turbo Drain Kit. Our Duramax oil drain line will work on any 2001-2016 Duramax. We use high quality braided stainless lines with billet aluminum adapters for both engine and turbo end of the lines.

The turbo oil drain flange at the turbo has a high-quality O-ring seal instead of the cheap factory paper gasket. This not only helps ease of install but provides a better seal.
