Whether you're a weekend warrior or a track-day enthusiast, these bearings are built to withstand the rigors of high RPM conditions.

Fitment

These bearings are compatible with a variety of popular engine configurations, ensuring that you get the best fit for your specific application. Always verify fitment for your particular engine year, make, and model to ensure optimal performance.

Features

  • High strength overlay plate with reduced thickness enhances fatigue properties for longer-lasting performance.
  • Hardened steel backs on all rod bearings improve support and retention in the housing.
  • Increased crush for superior bearing retention, keeping your bearings securely in place even under stress.
  • Elimination of flash plating enhances heat transfer and maximizes grip between the bearings and housing.
  • Increased eccentricity compensates for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings optimize load-carrying surface area and oil flow to conrod bearings.
  • Tight, consistent wall tolerances help maintain precise clearances for better performance.
  • Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts.
