The ACL 6B2455H-.025 is engineered specifically for the Porsche 911 Classic models from 1963 to 1977, making it a vital component for those looking to enhance their engine's performance. This rod bearing set is designed to meet the demanding needs of high RPM conditions while ensuring durability and reliability.

Key Features

  • Trimetal Construction: The unique design incorporates a high-strength overlay plate with reduced thickness, enhancing fatigue resistance and longevity under stress.
  • Hardened Steel Backs: Each rod bearing features hardened steel backs that provide superior support for the bearing lining, ensuring excellent retention within the housing.
  • Increased Crush: The bearings exhibit increased crush to improve retention, minimizing the risk of movement during operation.
  • Optimized Heat Transfer: Flash plating is eliminated on the back of the bearings, which enhances heat dissipation and maximizes grip between the bearings and their housing.
  • Enhanced Eccentricity: This feature compensates for bore distortion at high RPMs, facilitating the formation of hydrodynamic oil films for better lubrication.
  • 3/4 Grooved Design: The main bearings are designed with a 3/4 groove to optimize the load-carrying surface area and improve oil flow to the connecting rod bearings.
  • Tight Wall Tolerances: Consistent wall tolerances maintain reliable clearances, essential for high-performance applications.
  • Enlarged ID Chamfers: Where necessary, the bearing edges are chamfered to accommodate large fillet radii on performance crankshafts.
