PPE HD Cast Aluminum Engine Oil Pan - Black Finish (2020-2026 GM 3.0L Duramax) - (114054020
Overview
The PPE Heavy-Duty Cast Aluminum Engine Oil Pan in a sleek black finish is a major upgrade for 2020-2026 GM 3.0L Duramax engines. Built from A356.0-T6 heat-treated aluminum, this deep pan boosts oil capacity by 2 quarts, improves cooling efficiency, and provides superior durability compared to the factory steel pan.
A redesigned flat, angled bottom and a lower drain plug location ensure complete oil drainage, eliminating the half-quart of contaminated oil that remains trapped in the OEM pan. Reinforced gussets, machined cooling channels, and a magnetic drain plug all contribute to better engine protection and longer service intervals.
Key Features & Benefits
- Premium A356.0-T6 cast aluminum for strength, rigidity, and thermal performance
- Permanent steel mold casting for consistent finish and dimensional accuracy
- Increases oil capacity by 2 quarts for improved thermal stamina
- Machined longitudinal cooling channels maximize heat dissipation
- Cast-in gussets reinforce the upper flange for added structural support
- Precision-machined sealant grooves ensure proper RTV application and a reliable seal
- Includes stainless steel drain plug with high-temperature neodymium magnet
- Features a 1/8-inch NPT port for optional temperature sensors
Designed for Complete Oil Drainage
The OEM GM pan positions the drain plug above the lowest point, leaving behind sludge and metal contaminants. PPE's redesigned bottom profile places the drain plug below the pan floor, ensuring every oil change starts with a clean sump.
Cooling & Performance Advantages
Machined exterior grooves increase surface area and help stabilize oil temperatures under load. The included billet stainless steel magnetic drain plug captures ferrous debris before it can circulate through the engine, offering protection the factory plug cannot match.
Real-World Capacity Gains
PPE testing on the LM2 platform showed an increase from 7 quarts (OEM pan + filter) to 9.5 quarts when paired with the PPE Deep Oil Pan and PPE Premium Oil Filter (114000650).
