Product Description
The CUMMINS 4089093 OEM ENGINE OIL PAN (KIT) is the factory-correct replacement for any 1994–2002 5.9L Cummins 12-valve or 24-valve engine. If your original stamped-steel pan is rusting, leaking, dented, or contaminated from years of use, this genuine Cummins replacement restores proper oil sealing, structural rigidity, and long-term corrosion resistance.
As an OEM piece, this pan is built with the exact material grade, capacity, and flange alignment your engine was designed for. No sealing guesswork, no aftermarket fitment inconsistencies — just a smooth installation and a leak-free result. Whether you’re resealing the bottom end or finishing a full engine refresh, the 4089093 kit ensures factory-level performance.

FAQ
Is this a genuine Cummins oil pan and not aftermarket?
Yes — this is the OEM Cummins oil pan, part number 4089093, manufactured to factory specifications for the 1994–2002 5.9L Cummins platform. Does this fit both 12V and 24V Cummins engines?
Yes. It fits all 5.9L 12-valve (1994–1998) and 24-valve (1998.5–2002) Ram 2500/3500 engines with the standard steel front-sump configuration. Does the kit include the oil pan gasket?
The gasket is not included by Cummins. We recommend adding the OEM CUMMINS 3929693 OIL PAN GASKET.
Do I need to replace the oil pickup tube when replacing the pan?
It is not required, but if your pickup tube shows wear, denting, or sludge buildup, replacing it with the OEM CUMMINS 3949810 is recommended.
