GMC Sierra 2500HD Oil Pan - Wehrli - High Capacity Aluminum - Illusion Blueberry - `20-`25. This cast aluminum pan replaces the factory steel unit with a flat-bottom, higher-capacity design for 2020-2025 L5P Duramax applications.

Made from A356.0-T6 aluminum, this WCFab x PPE pan adds 2 extra quarts to help control oil temps, reduce high-RPM oil starvation, and extend oil life between changes. The flat bottom eliminates the stock pan’s valley that traps dirty oil below the drain, so used oil exits fully. An unshrouded pickup area supports stable pressure. Includes new fasteners, an 1/8 NPT port for sensors, and a billet stainless magnetic drain plug. Finished in Illusion Blueberry powder coat.
