Clevite CB-675H-10 H-Series Engine Connecting Rod Bearing Pair

Clevite CB-675H-10 H-Series connecting rod bearings are engineered for high-performance and competition engines, offering the ideal balance of durability and precision for medium to high RPM applications. These bearings feature tri-metal construction with a hardened steel back for exceptional strength and resistance to fretting under demanding conditions.

H-Series Performance Features:

• Medium eccentricity design provides optimal contact patterns covering 2/3 to 3/4 of bearing surface
• High crush construction ensures maximum retention in the rod bore
• Thin overlay with reduced thickness prevents overlay fatigue and "hen tracking"
• Enlarged chamfers provide greater crankshaft fillet clearance for oversized fillets
• Hardened steel backing delivers added strength for high-stress racing applications
• No flash plating for improved seating and bedding characteristics
• Without dowel holes for use in standard steel connecting rods

Ideal Applications:

H-Series bearings are the preferred choice for NASCAR-type racing and general competition engines running in medium to high RPM ranges. Use these bearings with crankshafts featuring oversize fillets, or when P-Series bearings produce contact patterns that are too narrow. If you're unsure which performance bearing series to select, H-Series bearings are the recommended starting point for most racing applications.

Quality Construction:

Clevite rod bearings meet or exceed OEM standards for strength and durability, with superior materials that protect vital engine components from the harmful effects of friction. The tri-metal construction combines a hardened steel back, intermediate layer, and precision overlay for the perfect combination of strength, conformability, and wear resistance.

Important Note: 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 8-cylinder engine).
