Upper Connecting Rod Bearings 30pk

The MAHLE ORIGINAL/CLEVITE Upper Connecting Rod Bearings 30-pack (CB1512VCTU) is a precision OEM-specification bearing set engineered for Mopar 426 Hemi and RB-series V-8 engine applications. These upper-only connecting rod bearings meet strict factory tolerances and deliver the reliability demanded in high-performance and restoration builds where engine integrity is non-negotiable.

Connecting rod bearings operate under extreme pressure and temperature cycling, requiring precision manufacturing and material composition that maintain clearance and load capacity across thousands of combustion cycles. The V-series designation on this set indicates a standard size and bearing geometry optimized for the RB-block architecture. With thirty individual upper bearings per pack, buyers can service a complete engine or maintain a spare inventory for multiple projects or rebuild scenarios. The compact packaging—1.82 pounds across standard shipping dimensions—suits warehouse storage or mobile engine-rebuild operations.

This bearing set is essential for engine rebuilders, restoration shops, and enthusiasts working on classic muscle cars and vintage Mopar platforms. Buyers sourcing replacement bearings for 426 Hemi rebuild kits, machine shop projects, or preventive maintenance on original engines depend on OEM-equivalent bearing stock to avoid repeat disassembly. MAHLE ORIGINAL and CLEVITE are recognized bearing manufacturers with long-standing presence in the OEM and aftermarket engine-rebuild sector, providing confidence in material and fitment specifications.

Selecting OEM-spec bearings—rather than generic or under-spec alternatives—ensures proper oil film strength, dimensional consistency, and long-term engine durability. The 30-pack format provides flexibility for complete engine builds, replacement inventories, or business stock for machine shops and performance engine builders specializing in big-block Mopar platforms.
