Upper Main Bearings Only Coated 9pk

The MAHLE ORIGINAL/CLEVITE Upper Main Bearings Only Coated 9-pack (MB3249VCTU) represents the factory-engineered bearing solution for high-displacement big-block Mopar engines, specifically the legendary 426 Hemi platform. These are upper main bearings only—the critical upper race components that carry crankshaft load directly from the engine block. The V-Series designation indicates these are precision-engineered for the Hemi's demanding lubrication and load characteristics, and the coated construction provides superior corrosion resistance and reduced wear under sustained operation.

These bearings ship as a complete 9-piece set—the exact quantity required for a full upper main bearing installation on the 426 Hemi block. The coating technology extends bearing life by reducing direct metal-to-metal contact and improving oil film retention under high RPM and sustained load. Standard bore geometry ensures drop-in compatibility without requiring line boring or modification. Proper installation requires torque specification adherence and correct orientation to maintain critical clearances that govern crankshaft runout and oil pressure distribution.

This bearing set is specified for full engine rebuild, racing application preparation, or replacement of worn original bearings. Whether rebuilding a 426 Hemi for street duty, restoration work, or high-output performance service, OEM-equivalent bearings eliminate compatibility guesswork and deliver the load-carrying capacity the block design expects. Operators familiar with Mopar big-block architecture recognize MAHLE ORIGINAL/CLEVITE as the engine bearing standard across Chrysler factory service specifications.
