The ACL Bearings 8B1663HXC-STD is a high-performance coated connecting rod bearing set designed for custom V8 performance engine builds. This Race Series bearing set features ACL's advanced Calico CT-1 dry film lubricant coating, providing superior protection and performance under extreme conditions.

Key Features:

• Calico CT-1 coated bearing surfaces for enhanced wear resistance and reduced friction
• Premium tri-metal construction with hardened steel backing for improved bearing retention
• Designed for 1.889" journal diameter with 0.792" bearing width
• HXC designation indicates extra oil clearance (.001" additional clearance)
• Standard (STD) size for use with standard crankshafts
• Set includes 8 rod bearing pairs for complete V8 engine applications
• High-strength overlay with reduced thickness for improved fatigue properties
• Increased bearing crush for superior retention and resistance to bearing spin

ACL Race Series bearings are engineered to withstand higher RPM conditions and extreme loads in motorsports applications. The CT-1 coating provides intermittent dry lubrication during cold starts and high-stress conditions, helping to reduce oil temperatures and protect against metal-to-metal contact. These bearings are ideal for custom performance builds, race engines, and high-horsepower street applications requiring precise bearing clearances and maximum durability.
