GMC Sierra HD Oil Pan - Wehrli - High Capacity, WCFab X PPE - Semi-Gloss Black - 11-16. This cast aluminum pan is a high-capacity, service-friendly upgrade that replaces the factory steel unit on 2011–2016 GM Duramax platforms.

Made from A356.0-T6 cast aluminum with a durable semi-gloss black powder coat, it uses a flat-bottom design to drain the dirty oil the stock pan leaves behind. Extra capacity helps oil cooling and pressure stability under towing or high RPM. The unshrouded pickup area supports consistent pressure, while thick walls allow drilling and tapping for aftermarket turbo oil returns. An integrated 1/8 in NPT port simplifies sensor installs, and the included billet stainless magnetic drain plug (neodymium) captures fine metal. Hardware and NPT plug are included.
