GMC Sierra 2500HD Oil Pan - Wehrli - High Capacity, WCFab X PPE - Gloss Black - 2020–2026. A cast aluminum, high-capacity replacement for the stock steel pan on L5P Duramax trucks, engineered for better draining and dependable lubrication.

This A356-T6 cast pan replaces the factory design that traps over half a quart of dirty oil below the drain, using a flat-bottom layout for a more complete service. With an additional 2 quarts of capacity, it helps keep oil cooler, helps prevent high-RPM oil starvation, and can extend oil life between changes. Finished in durable gloss black powder coat, it includes new fasteners, an NPT plug, and a billet stainless steel magnetic drain plug with a neodymium magnet. An unshrouded pickup area supports oil pressure, while the 1/8 in. NPT port simplifies sensor installs. Thick walls allow drill-and-tap for turbo oil drains. Fits 2020–2026 GMC Sierra 2500HD with L5P Duramax.
