ACL Main Bearing Set 5M2747A-STD for Nissan KA24E/DE 1989-2002, Tri-Metal Design - 5M2747A-STD

If you're looking to give your engine the kind of bearings that can handle some serious RPM, the ACL Race Series Engine Bearings are where it's at. These aren't your average bearings; they’re crafted from a unique blend of design and metallurgy that really holds up under pressure. Perfect for a variety of 4, 6, and 8-cylinder engines, these bearings are built to last and perform.

Features You’ll Appreciate:

  • High Strength Overlay: The thinner overlay plate means better fatigue properties, so you can push your engine without worrying about wear and tear.
  • Hardened Steel Backs: All rod bearings come with hardened steel backs, making sure the lining stays put and gives you solid support in the housing.
  • Increased Crush: This helps with bearing retention, so you can be confident that everything stays where it should be.
  • No Flash Plating: We’ve ditched the flash plating on the backs of these bearings. This means better heat transfer and a more secure grip in the housing—no slipping here!
  • Increased Eccentricity: Designed to handle bore distortion at high RPMs, these bearings help in forming hydrodynamic oil films, which is crucial for performance.
  • 3/4 Grooved Main Bearings: This design optimizes the load-carrying surface area and improves oil flow to the conrod bearings, keeping everything lubricated just right.
  • Tight Wall Tolerances: Consistent clearances mean you can trust that your setup is dialed in.
  • Enlarged ID Chamfers: These are tailored for performance crankshafts, accommodating larger fillet radii where needed.
