Cosworth PR7655 Performance Main Bearing Set (Size 2) - RB25 RB26

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 2 is what we used to call "RACE"

• Size 2 provides .025mm or .001" more oil clearance than our size 1 bearing

Bearings are sold in sets only.
