Clevite CB-1357P High Performance P-Series Rod Bearing Set

The Clevite CB-1357P is a high-performance P-Series connecting rod bearing set designed for demanding racing and performance applications. These precision-engineered bearings feature TriMetal construction with a hardened steel back for maximum strength and resistance to fretting, making them ideal for engines operating at extremely high RPMs.

P-Series Performance Features:

• Maximum eccentricity design prevents severe rod bore close-in at high RPM
• Hardened steel back construction for superior strength and durability
• High crush design ensures maximum bearing retention in the rod
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Lead-tin-copper overlay provides excellent wear resistance
• Enlarged chamfers for improved crankshaft fillet clearance
• Available with or without dowel holes for aluminum rod applications

Application Notes:

P-Series bearings are Clevite's original high-performance bearing line, engineered specifically for extreme racing conditions where rod bore distortion is a concern. The high eccentricity design helps maintain proper oil film thickness and prevents the parting line-to-parting line contact that occurs with standard bearings at extreme RPM. These bearings are ideal for applications showing signs of rod bearing oil starvation, indicated by bearing surface polishing, smearing, or discoloration concentrated at the axial center.

Each set includes two bearing halves for one connecting rod journal. The TriMetal construction bonds a lead-tin-copper overlay to an aluminum-tin intermediate layer on a hardened steel backing, providing the perfect balance of strength, conformability, and wear resistance for high-performance engines.

IMPORTANT: Clevite rod bearings are sold as paired sets (two bearing halves for one rod). For a 6-cylinder engine, order quantity 6. For a V8 engine, order quantity 8.
