ACL Race Series Engine Bearings - 5M909P-20

If you’re looking to push your engine’s limits while maintaining reliability, the ACL Race Series Engine Bearings (5M909P-20) are engineered for high-performance applications. These bearings are designed with a unique combination of advanced metallurgy and precision engineering, making them an ideal upgrade for your Chevrolet Camaro (1975-2002, 2010-2021) or Chevrolet Caprice (1975-1996, 2000-2017). Whether you're hitting the track or just enjoying spirited drives, these bearings will help you achieve optimal performance.

Key Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance, ensuring longevity under high RPM conditions.
  • Hardened steel backs on all rod bearings provide superior support for the bearing lining, improving retention within the housing.
  • Increased crush allows for better bearing retention, crucial for high-stress applications.
  • Eliminates flash plating on the back of bearings to optimize heat transfer and grip within the housing.
  • Enhanced eccentricity compensates for bore distortion at elevated RPMs, promoting effective hydrodynamic oil film formation.
  • 3/4 grooved main bearings maximize load-carrying surface area and improve oil flow to the connecting rod bearings.
  • Tight wall tolerances help maintain consistent clearances, which is vital for performance engines.
  • Enlarged ID chamfers accommodate larger fillet radii on performance crankshafts, ensuring compatibility with aftermarket builds.
