Chevrolet Duramax Oil Pan - Wehrli High Capacity Aluminum, WCFab X PPE - Illusion Blueberry (2001–2010). A cast-aluminum replacement for LB7, LLY, LBZ, and LMM trucks that improves draining and durability.

Built from A356.0‑T6 cast aluminum with a flat-bottom profile, this WCFab X PPE pan fixes the factory valley that traps dirty oil for a proper drain. The extra quart helps keep oil cooler, reduces high‑RPM starvation risk, and can extend oil life between changes. Thick walls accept drilling/tapping for turbo drains, and a 1/8" NPT port simplifies temp sensors. Includes hardware, an NPT plug, and a billet stainless drain plug with a neodymium magnet.
