GMC Sierra 2500HD Engine Oil Pan - Wehrli - High Capacity WCFab X PPE Aluminum - Gloss White - 2011–2016. A purpose-built cast aluminum upgrade for LML Duramax Sierra 2500HD that improves drainback and capacity versus the factory steel pan.

The flat-bottom design eliminates the stock valley that traps dirty oil, allowing more complete draining at service. Added volume (about one extra quart) supports cooler temps, helps reduce high‑RPM starvation, and can extend oil life. Cast from A356.0‑T6 aluminum with a durable gloss white powdercoat, it includes required fasteners, an NPT plug, and a billet stainless drain plug with a neodymium magnet. An unshrouded pickup area helps maintain oil pressure, a 1/8 in. NPT port simplifies temp sensors, and the thick wall accepts drilling and tapping for aftermarket turbo drains.
