GMC Duramax Oil Pan - Wehrli High Capacity Aluminum, WCFab X PPE - WCFab Grey (2020-2025). A flat-bottom cast-aluminum upgrade that replaces the stock steel pan and adds capacity.

Cast from A356.0-T6 aluminum and finished in WCFab Grey, this pan adds 2 extra quarts to help control oil temps, reduce high-RPM oil starvation, and lengthen service intervals. The flat bottom eliminates the stock valley that traps dirty oil, while the unshrouded pickup supports steady pressure. Thick walls accept drilling and tapping for turbo oil drains. Includes fasteners, 1/8 in. NPT port and plug, plus a billet stainless drain plug with a neodymium magnet.
