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 setsare available in two sizes to accommodate most applications. Size “1” bearings are a nominal standard size and are used for most applications. Size “2” bearings feature an additional .001” clearance and should be used
when extra clearance is required.
