The MAHLE ORIGINAL/CLEVITE Upper Rod Bearings (CB1512VU) represent OEM-grade connecting rod bearing components engineered for Mopar 426 Hemi and RB-series V8 engines. This 30-piece set provides standard-size upper bearings essential for engine rebuild and performance restoration work. These precision-manufactured bearings meet factory specifications and are constructed to the exacting tolerances required for heavy-duty automotive applications where bearing clearance and load distribution are critical to engine longevity and reliability.

Each bearing is manufactured using proprietary materials and coating technologies developed by MAHLE, a Tier 1 automotive supplier with decades of OEM powertrain component experience. The V-Series designation indicates these bearings are optimized for the specific journal geometry and load profile of V8 applications. The standard size means these bearings are designed for engines in stock specification or those with minimal bore work. The set of 30 provides ample quantity for full engine assembly or service inventory, with each bearing individually produced to maintain consistency across the entire package.

Engine builders, machine shops, and serious automotive enthusiasts restoring 426 Hemi and RB-block engines rely on OEM-specification bearings to ensure correct clearances and proper oil film establishment during break-in. These MAHLE ORIGINAL/CLEVITE bearings are appropriate for stock rebuilds, restorations, and performance applications where factory bearing specifications are required. The compact packaging (1.5 x 3 x 11.5 inches) makes storage and inventory management straightforward for shop environments.

Mopar 426 Hemi and RB-series engines remain core to classic muscle car and hot rod builds. Connecting rod bearing selection directly affects engine reliability and performance characteristics. MAHLE's position as an OEM supplier for Chrysler powertrains means these bearings carry the same engineering validation used in factory engine assembly, making them a reference standard for bearing quality in this engine family.
