GMC Sierra 2500HD Oil Pan – Wehrli High Capacity Aluminum, WCFab X PPE, WCFab Red, for 2017–2019 L5P Duramax. This cast pan replaces the factory steel unit with a flat-bottom design that drains completely and services easily.

Made from A356-T6 cast aluminum, it adds about 2 extra quarts to help control oil temps and reduce the chance of high‑RPM oil starvation. The flat bottom clears out the old oil the stock pan leaves behind. Includes new hardware, an NPT plug, and a billet stainless steel magnetic drain plug to capture fine metal. A 1/8 in. NPT port simplifies temp sensor installs, thick walls accept drilling/tapping for turbo oil drains, and the unshrouded pickup area helps maintain consistent pressure. Durable WCFab Red powdercoat matches WCFab components.
