Product Details

The ACL Bearings 4M2273A-1.00 is a complete standard main bearing set engineered for high-performance and racing engine applications. These precision-machined main bearings feature ACL's proprietary Aluglide bearing material, which provides exceptional wear resistance and load-carrying capacity under extreme operating conditions.

Key Features:

  • Aluglide tri-metal construction with aluminum-tin overlay for superior conformability and embedability
  • Standard size (1.00mm oversized) for proper crankshaft clearances during performance rebuilds
  • High fatigue strength steel backing for dimensional stability
  • Optimized bearing profile for consistent oil film thickness
  • Manufactured to OE specifications with tighter tolerances for racing applications
  • Complete main bearing set for full engine assembly

ACL Race Series bearings are designed for professional engine builders and performance enthusiasts who demand reliability under high loads, extreme temperatures, and elevated RPM conditions. The Aluglide material provides excellent protection during cold starts and the ability to handle higher bearing loads compared to conventional babbitt bearings.
