GMC Sierra 2500HD Oil Pan - Wehrli High Capacity Aluminum - Cat Yellow - 2020–2026. A cast-aluminum upgrade that improves draining and capacity for your L5P Duramax.
Built with WCFab x PPE, this A356.0‑T6 cast pan adds about 2 extra quarts over stock to help oil run cooler, reduce high‑RPM starvation, and extend service intervals. The flat-bottom design eliminates the factory valley that traps dirty oil, and an unshrouded pickup area supports stable pressure under load. Includes pan, hardware, NPT plug, and a billet stainless steel neodymium magnetic drain plug.
