GMC Sierra Oil Pan – Wehrli High Capacity Aluminum, WCFab X PPE – Sparkle Bomber Orange (2020–2025). A cast A356.0‑T6 upgrade for 6.6L L5P Duramax that increases capacity and corrects the stock drain design.

The factory steel pan’s valley traps old oil. This flat‑bottom pan drains fully and adds 2 extra quarts to help keep oil cooler, maintain pressure at high RPM, and extend service life. Includes fasteners, an NPT plug, and a billet stainless magnetic drain plug with a Neodymium magnet. A 1/8 in NPT port accepts temp sensors, thick walls can be drilled/tapped for turbo returns, and the unshrouded pickup area promotes stable pressure. Finished in Sparkle Bomber Orange powder coat.
