Upgrade your 2020-2026 L5P Duramax with the Wehrli WCF100134-GW High Capacity Oil Pan, developed in collaboration with PPE for maximum performance and reliability. Constructed from thick cast aluminum, this oil pan replaces the restrictive factory steel design with a flat-bottom configuration that improves oil drainage and reduces contamination. By eliminating the factory valley that traps dirty oil, this design ensures cleaner oil circulation and extends engine life. With an additional 2 quarts of oil capacity and a durable gloss white powder coat finish, this pan is built for both performance and style. Includes all necessary hardware along with a billet stainless steel magnetic drain plug for enhanced protection.
