Chevrolet Silverado 3500HD Oil Pan – Wehrli High Capacity Aluminum, WCFab X PPE, WCFab Red (2017–2019). A cast A356.0‑T6 upgrade that replaces the stock steel pan with a flat-bottom, higher-capacity design for cleaner service and dependable lubrication.

Engineered for the 2017–2019 L5P Duramax, this pan adds about 2 extra quarts to help manage oil temps, reduce high‑RPM starvation risk, and extend service intervals. The flat floor drains the dirty valley left by the OEM pan. Thick walls accept drill-and-tap for turbo drains, and the unshrouded pickup area supports stable pressure. Includes pan, fasteners, NPT plug, and a billet stainless magnetic drain plug. Durable WCFab Red powder coat.
