Product Details

ACL Bearings 4B1269A-40 Standard Connecting Rod Bearings deliver race-proven durability and precision engineering for high-performance engine builds. These connecting rod bearings feature ACL's advanced trimetal construction, combining a hardened steel backing with copper-lead alloy lining and a high-strength overlay plate designed to withstand elevated RPM conditions and extreme operating temperatures.

Key Features:

  • Trimetal construction with hardened steel backing for superior bearing retention and support
  • High-strength overlay plate with reduced thickness for improved fatigue resistance
  • Elimination of tin flash plating on bearing backs for enhanced heat transfer and better housing grip
  • Precision-manufactured to tight wall thickness tolerances for consistent bearing clearances
  • Increased eccentricity to compensate for bore distortion at high RPM
  • Enlarged ID chamfers on bearing edges to accommodate performance crankshaft fillets
  • Standard size bearings designed for OEM crankshaft journal specifications

ACL's unique combination of metallurgy and engineering delivers the performance and reliability that engine builders demand. These bearings optimize oil flow and load-carrying capacity while reducing friction and operating temperatures, making them ideal for street performance, racing, and engine rebuilds where superior quality is essential.
