ACL 10B1580H-.25 Performance Rod Bearing Set

The ACL 10B1580H-.25 rod bearing set is engineered for high-performance applications, particularly suited for the BMW S85B50 engine. This set features advanced metallurgy and design principles that cater to the demands of high RPM operation, making it an excellent choice for both street and track use.

Key Features

  • Constructed with a high-strength overlay plate that has a reduced thickness, enhancing fatigue resistance and longevity under extreme conditions.
  • All rod bearings are equipped with hardened steel backs, providing enhanced support for the bearing lining and improving retention within the housing.
  • Increased crush design ensures superior bearing retention, minimizing the risk of movement under load.
  • Flash plating has been eliminated on the back of the bearings, which significantly improves heat transfer and maximizes grip between the bearings and their housings.
  • Increased eccentricity is incorporated to counteract bore distortion at high RPMs, aiding in the formation of hydrodynamic oil films for optimal lubrication.
  • 3/4 grooved main bearings optimize the load-carrying surface area and enhance oil flow to the connecting rod bearings.
  • Tight and consistent wall tolerances ensure uniform clearances, which is critical for performance applications.
  • Enlarged ID chamfers on bearing edges accommodate large fillet radii found on performance crankshafts, allowing for better fitment and reliability.

Specifications

  • Size: .25mm Oversized
  • Oil Clearance: Standard
  • Half Type: Identical Halves
  • Material: Tri-metal with Hardened Steel Backs
