ACL 4B1946A-.50 Oversized Rod Bearing Set

The ACL 4B1946A-.50 is engineered to meet the demands of high-performance engines, particularly in the Honda and Acura platforms. This rod bearing set features a tri-metal construction that combines strength and durability, making it suitable for high RPM applications.

Key Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance, ensuring longevity under intense conditions.

  • Increased crush design enhances bearing retention, minimizing the risk of movement during operation.
  • Elimination of flash plating on the back of the bearings improves heat transfer, maximizing grip between the bearing and housing.
  • Increased eccentricity compensates for bore distortion at high RPM, aiding in the formation of hydrodynamic oil films for optimal lubrication.
  • 3/4 grooved main bearings optimize load-carrying surface area and oil flow to conrod bearings.
  • Tight wall tolerances ensure consistent clearances, which is critical for performance applications.
  • Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts.
