ACL Bearings 8B745H-10 H-Series Rod Bearing Set Small Block Chevy .010 Undersize

The ACL Bearings 8B745H-10 is a high-performance connecting rod bearing set engineered for small block Chevy 265, 283, and 327 cubic inch V8 engines with small journal (2.000" diameter) crankshafts. This set features a .010" undersize dimension designed for reground crankshafts, making it ideal for engine rebuilds and performance applications.

Race-Proven H-Series Design:

• Tri-metal construction with lead, tin, copper, and nickel for superior strength and seizure resistance
• Hardened steel backing on all rod bearings for improved support and retention
• High-strength overlay plate with reduced thickness for enhanced fatigue properties
• Increased eccentricity to compensate for bore distortion at high RPM operation
• Chamfered edges to accommodate larger fillet radii on performance crankshafts

Precision Manufacturing:

• Micron tolerance machining ensures consistent wall thickness and crush specifications
• No flash plating on bearing backs for improved heat transfer and maximum grip
• Tight dimensional tolerances help maintain consistent bearing clearances
• Manufactured in Australia to exacting quality standards

ACL H-Series bearings are designed specifically for medium to high RPM performance engines and forged crankshafts. The .010" undersize compensates for crankshaft journals that have been machined .010" smaller than standard specifications during engine rebuilding or performance balancing.
