ACL Bearings 8B745HXN-STD H-Series Connecting Rod Bearing Set Small Block Chevy Narrowed 2.000" Journal

The ACL Bearings 8B745HXN-STD is a high-performance connecting rod bearing set designed for Small Block Chevy engines with a 2.000" crankshaft journal diameter. This H-Series bearing set features a narrowed design for specialized applications requiring reduced bearing width, combined with extra oil clearance for optimal performance in racing and high-RPM conditions.

Key Features:

• H-Series Race performance construction with tri-metal design (steel backing, copper-lead intermediate layer, tin overlay)
• Narrowed bearing width for specific stroker and aftermarket crankshaft applications
• Extra oil clearance design - bearings are 0.0005" thinner per half to provide 0.001" additional clearance
• 2.000" journal diameter - standard size for Small Block Chevy 265-327 and aftermarket forged crankshafts
• Hardened steel backing on all rod bearings improves bearing retention and support
• High-strength overlay plate with reduced thickness for improved fatigue resistance
• Increased crush for superior bearing retention in the housing
• Precision machined to micron-level tolerances for consistent wall thickness and crush
• Manufactured in Australia to exacting ACL Race Series specifications

ACL Race Series bearings are engineered to withstand the extreme demands of high-performance and racing applications. The extra clearance specification is ideal for engines running synthetic oils, high-RPM operation, or applications requiring slightly looser bearing clearances for optimal oil film formation.
