GMC Sierra Oil Pan – Wehrli High Capacity, WCFab X PPE – Sparkle Granny Smith (2011–2016). A precision cast aluminum replacement for the factory steel pan that adds capacity and improves drain-out on LML Duramax platforms.

Made from A356.0-T6 aluminum, this flat-bottom design removes the OE valley that traps dirty oil below the plug. The added capacity (about an extra quart) helps oil run cooler, reduces the chance of high-RPM starvation, and can extend intervals between changes. An unshrouded pickup area supports steady pressure, while thick walls accept drilling/tapping for aftermarket turbo oil returns. Kit includes new fasteners, an NPT plug, and a billet stainless steel neodymium magnetic drain plug, plus a 1/8 in. NPT port for sensors or accessories.
