The Cummins N14 is the legendary “Million Mile Engine,” but reaching that milestone requires a bottom end capable of handling immense torque. Our Cummins N14 Main Bearing Sets are precision-engineered to restore oil pressure and crankshaft stability in both N14 Celect and Celect Plus models. Designed as a direct replacement for OEM 3802070, these bearings are the standard for heavy-duty overhauls in Peterbilt 379s and Kenworth W900 haulers.
Ruich Value manufactures these bearings using a high-load Copper-Lead Tri-Metal material, essential for withstanding the high compression ratios of the 14-liter platform. Whether you are an engine rebuilder servicing fleet trucks or a farmer maintaining a Case IH Steiger tractor, our aftermarket solution delivers OEM-level durability at a wholesale price point.
