ACL Bearings 8B663PO/S2-40 Performance Connecting Rod Bearing Set

The ACL Bearings 8B663PO/S2-40 is a precision-engineered connecting rod bearing set designed for high-performance engine applications. ACL Race Series bearings feature advanced tri-metal construction with a steel backing, aluminum-tin alloy intermediate layer, and a polymer coating for enhanced durability and reduced friction.

Key Features:

• Tri-metal construction with polymer overlay for superior wear resistance
• Standard size (STD) bearings with high-performance coating
• Precision manufacturing to tight tolerances for optimal oil clearance
• Enhanced load capacity for demanding applications
• Designed for use in performance and racing engines

This connecting rod bearing set provides the reliability and performance characteristics required for modified engines operating under high stress and elevated RPM conditions. The polymer coating reduces friction and protects against scuffing during cold starts and high-load situations.
