Fitment

These bearings are compatible with a range of popular makes and models. Always verify fitment based on your specific engine application to ensure optimal performance.

Key Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance, making these bearings suitable for intense driving conditions.
  • Hardened steel backs on all rod bearings provide superior support for the bearing lining, ensuring they stay securely in place within the housing.
  • Increased crush enhances bearing retention, preventing any unwanted movement during operation.
  • Elimination of flash plating on the back improves heat transfer, maximizing the grip between the bearings and their housing.
  • Increased eccentricity compensates for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films for better lubrication.
  • 3/4 grooved main bearings optimize load-carrying surface area and enhance oil flow to the connecting rod bearings.
  • Tight, consistent wall tolerances help maintain precise clearances, crucial for performance engines.
  • Enlarged ID chamfers on bearing edges accommodate larger fillet radii found on performance crankshafts.
