GMC Sierra Oil Pan - Wehrli - High Capacity, Aluminum, WCFab X PPE - Cat Yellow - 11–16. Cast A356.0-T6 aluminum pan that replaces the stock steel unit with added volume and a flat-bottom for cleaner, more complete draining.

Built for 2011–2016 GM Duramax (LML) trucks, this WCFab x PPE pan adds about one extra quart to help control oil temps and reduce high‑RPM starvation. The flat bottom removes the OEM valley that traps dirty oil. Thick walls accept drill/tap turbo drains, a 1/8 in NPT port eases sensor installs, and the Cat Yellow powder coat ties into your build. Includes pan, fasteners, NPT plug, and a billet stainless magnetic drain plug to capture debris.
