GMC Sierra 2500HD Oil Pan - Wehrli High Capacity, WCFab X PPE, WCFab Red (2020-2025). A cast aluminum upgrade for L5P Duramax trucks that replaces the stock steel pan and improves serviceability.

Built from A356.0-T6 cast aluminum, this flat-bottom pan eliminates the OE valley that traps old oil, promoting a more complete drain and steadier oil pressure. Added volume (about 2 extra quarts) helps manage temps, reduces the risk of high-RPM starvation, and can extend oil life between changes. Supplied in WCFab Red with fasteners, an NPT plug, and a billet stainless magnetic drain plug that captures metal particles.

Features

• Approx. +2 qt capacity for added thermal buffer
• Flat-bottom design for proper oil evacuation
• Unshrouded pickup area to maintain pressure
• 1/8 in NPT port for temp sensors or accessories
• Thick-wall casting can be drilled/tapped for turbo drains
• Includes hardware and magnetic drain plug
