Industrial Injection BI591224VOP Big Iron Engine Oil Pan Cummins - 5.9L 12V/24V

The Industrial Injection Big Iron Oil Pan (BI591224VOP) is a heavy-duty replacement engine oil pan engineered for the 1989–2002 Dodge Ram 5.9L Cummins diesel, covering both the 12-valve and 24-valve variants. Built to strict quality control standards, this pan is a direct replacement that delivers improved durability and drainage over the factory oil pan.

Key Features:

• Four drain holes through the drain plug nut allow the pan to achieve a complete, full oil drain — no residual oil left behind
• Thicker, reinforced mounting lip for a more robust seal and improved structural integrity compared to the stock pan
• Requires 6.7L oil pan bolts (longer than standard 5.9L bolts) to accommodate the reinforced lip — sold separately as part number BI591224VOPB
• Direct replacement fitment — designed to install in place of the OEM pan with no cutting or modification required on 1994–2002 applications
• Built to strict quality control standards by Industrial Injection, a trusted name in diesel performance

Installation Note: When installing this pan on an 1989–1993 Cummins engine, a 1994–2002 style pickup tube is required. The extended oil pan bolt kit (BI591224VOPB), which includes 36 extended bolts, is recommended for proper mounting and is available separately.
