Clevite CB-1589H Engine Connecting Rod Bearing Pair

Performance Connecting Rod Bearings

Clevite CB-1589H is a high-performance engine connecting rod bearing pair built for standard-size applications that need stable oil film control and consistent seating. It fits a wide range of Nissan engines, including Frontier, Xterra, Altima, 240SX, Pickup, and D21 applications.

Key Features

• H-Series tri-metal construction for performance use
• Medium eccentricity and high crush for secure bearing fit
• Hardened steel back with a thin overlay
• Made without flash plating for improved seating
• Standard size with OE-specification compliance

Detailed Description

Clevite CB-1589H is part of the H-Series performance line, engineered for engines that operate in medium to high RPM ranges and for crankshafts with oversize fillets. The TM-77 bearing material, tri-metal construction, and standard sizing make it a practical choice when you need a performance-oriented connecting rod bearing that follows original equipment specifications. This part number, CB-1589H, is commonly selected for Nissan engine rebuilds where bearing fit and durability matter.

The H-Series line is focused on controlled clearance, strong backing support, and reliable seating under load. For Nissan Frontier and Nissan Xterra rebuilds, as well as Nissan Altima, 240SX, Pickup, and D21 applications, CB-1589H provides a standard-size solution for engines that need a performance-grade bearing set without changing the original bore size.

What It Is Used For

• Excessive bearing wear during engine rebuilds
• Loss of oil film stability in higher-RPM operation
• Poor bearing seating from flash-plated surfaces
• Fitment needs for standard-size connecting rod journals
• Performance rebuilds requiring tri-metal bearing construction

Installation Notes and Tips

Verify crankshaft journal condition, bearing clearance, and fillet radius before installation. CB-1589H is intended for engines with oversize fillets and should be matched to the correct standard-size application. Confirm Nissan fitment by year, model, and engine specification before assembly. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Clevite lists this bearing as meeting or exceeding original equipment manufacturer specifications. The H-Series design uses a hardened steel back and performance-focused construction for dependable engine rebuild service.
