Clevite CB-1598P-20 P-Series Rod Bearing Set

The Clevite CB-1598P-20 is a high-performance P-Series connecting rod bearing set designed for demanding engine applications. These precision-engineered bearings meet or exceed OEM standards for strength and durability while offering enhanced protection against the harmful effects of friction and wear.

P-Series Performance Features:

• Maximum eccentricity design prevents severe rod bore close-in at extremely high RPMs
• Hardened steel back construction provides added strength and resistance to fretting
• High crush design ensures maximum retention in the rod bore
• Reduced overlay thickness prevents overlay fatigue (hen tracking)
• .020" undersize for use with crankshafts machined .020" undersize
• TriMetal construction with lead-tin-copper overlay for superior durability

When to Use P-Series Bearings:

P-Series rod bearings are ideal for engines operating at extremely high RPMs where severe rod bore distortion occurs. The increased eccentricity helps maintain proper oil clearance and prevents full parting line contact with the crankshaft. These bearings are particularly effective when you've experienced bearing surface polishing, smearing, or discoloration concentrated at the axial center—classic signs of oil starvation caused by insufficient eccentricity.

Important Ordering Information:

Clevite rod bearings are sold as PAIRED SETS (two bearing halves for one connecting rod). For a 6-cylinder engine, order quantity 6. For an 8-cylinder engine, order quantity 8.
