Clevite CB-1409P-.25MM High Performance Connecting Rod Bearing Set

The Clevite CB-1409P-.25MM is a high-performance connecting rod bearing set featuring P-Series construction designed for extreme racing conditions and high-RPM applications. These bearings are engineered to exceed OEM standards with superior materials and precision manufacturing that protect vital engine components from friction and wear.

P-Series Performance Features:

• Maximum eccentricity design for severe rod bore close-in conditions at extremely high RPM
• Hardened steel back construction for added strength and fretting resistance
• High crush design ensures maximum bearing retention in the connecting rod
• Reduced overlay thickness prevents overlay fatigue and "hen tracking"
• Available with or without dowel holes for aluminum rod compatibility
• TriMetal bearing construction combines durability with performance

Undersize Specification: This bearing set is manufactured with a .25mm undersize dimension, designed for crankshafts that have been machined .25mm undersize from standard specifications. Critical for proper clearances when using reground or undersized crankshaft journals.

Ideal Applications: P-Series bearings are the preferred choice for engines experiencing severe rod bore distortion at high RPM, typically indicated by nearly full parting line contact. These bearings excel in competition engines, high-performance street builds, and any application where maximum bearing retention and oil flow are critical.

Important: Clevite bearings are sold as paired sets (two bearing halves for one connecting rod). For a complete engine rebuild, order one set per cylinder (e.g., quantity 6 for a 6-cylinder engine, quantity 8 for a V8).
