Cosworth Main Bearing Set - Evolution 10 4B11

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.


  • 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 Rod 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!
