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. Cosworth Race bearing sets feature a unique combination of design, metallurgy and engineering to deliver what drivers expect from high performance Trimetal engine bearings. Engineered with the following 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 •Tested to over 1000 horsepower!
