GMC Duramax Oil Pan - Wehrli - High-Capacity, Cast Aluminum, WCFab X PPE - Illusion Purple - '20-'25. A direct-fit upgrade for 2020–2025 L5P Duramax trucks that increases capacity and improves draining in a durable powder-coated finish.

Cast from A356.0-T6 aluminum, this flat-bottom pan addresses the stock valley that traps dirty oil, allowing a more complete drain. The design adds roughly two extra quarts to help manage oil temps, reduce the chance of high-RPM starvation, and support longer service intervals. An unshrouded pickup area promotes consistent pressure, and thick walls allow drilling and tapping for turbo oil drains. Includes hardware, an NPT plug, and a billet stainless magnetic drain plug to capture metallic particles. Color: Illusion Purple.
