More Info:
Engine bearings are one of the most vital components within an engine and are often overlooked when considering high performance upgrades. Performance engineered, multi-layer bearings generate less heat than normal bearings by reducing friction.

Features:
• High strength overlay plate with reduced thickness for better oil control and less friction
• Hardened steel backing on all connecting rod bearings
• Increased crush and elimination of flash plating
• 3/4 grooving on Main Bearings providing optimum oil supply
• Tight consistent wall tolerances
• Oversize chamfers where applicable
• Flash plating eliminated for improved heat transfer
• Tested to over 1000 horsepower!
