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 performance in extreme conditions. Cosworth Race bearings sets are available in three sizes to accommodate most applications.
Size 0 bearings have .001" less oil clearance than factory
Size 1 bearings are a nominal standard size and are used for most applications.
Size 2 bearings feature an additional .001" more oil clearance than factory
