Chevrolet Silverado Oil Pan – Wehrli High Capacity Aluminum, WCFab X PPE (WCFab Grey, 2011–2016). A cast upgrade for LML Duramax trucks that adds capacity and improves draining.

Cast from A356.0‑T6 aluminum with a flat bottom, it removes the factory valley that traps dirty oil for full drain-out. The extra quart helps cooling, reduces high‑RPM starvation risk, and can extend oil life. Includes fasteners, NPT plug, a billet stainless magnetic drain plug (Neodymium), and a 1/8 in. NPT sensor port.
