ACL Bearings 6B1160-STD Race Series Connecting Rod Bearing Set - Standard Size

The ACL Bearings 6B1160-STD is a Race Series connecting rod bearing set engineered for high-performance and racing applications. ACL Race Series bearings are recognized throughout the motorsports world as premium components in engines that have set records and won championships across various racing disciplines, from sport compact drift racing to NASCAR, IHRA, and NHRA competitions.

Race-Proven Performance Features:

• Tri-metal construction with hardened steel backing for superior strength and durability
• High-strength overlay plate with optimized thickness for improved fatigue resistance
• Precision-engineered to exacting tolerances for perfect fit and optimal performance
• Enhanced bearing retention through higher radial contact pressure
• Improved thermal transfer for more effective heat dissipation
• Full 180-degree grooved upper bearings with matching partial groove in lower shells
• Tapered groove run-out design smooths oil supply cut-off to avoid pressure pulsing
• Chamfered edges accommodate larger fillet radii on performance crankshafts

Technical Specifications:

• Standard size (STD) - designed for standard journal dimensions
• Recommended oil clearance: 0.00075-0.001 inch per inch of journal diameter plus 0.0005 inch
• Manufactured through precision electroplating process
• May exhibit dark tarnished coloration (black, brown, blue, or copper) from electroplated overlay - this is normal and does not affect performance

The unique combination of advanced metallurgy, precision engineering, and race-tested design provides ACL Race Series bearings with the endurance and capability to perform in high-RPM, high-load conditions where standard bearings cannot. These bearings are ideal for engine rebuilds, performance upgrades, and competition applications requiring maximum reliability and longevity.
