ACL Nissan KA24E/DE 0.50mm Oversized Main Bearing Set for 1989-2002 240SX S13/S14 - 5M2747A-.50

If you’re diving into the world of high-performance engines, you know that not all bearings are created equal. That’s where these ACL Race Series Engine Bearings come into play. They’ve got the right mix of design, metallurgy, and engineering to handle those high RPMs without breaking a sweat. Perfect for a range of 4, 6, and 8-cylinder setups, these bearings are built to last and keep your engine running smoothly.

What Makes These Bearings Stand Out?

  • High Strength Overlay: The overlay plate is thinner but tougher, which means it can handle more fatigue. You’ll notice the difference when you push your engine to its limits.
  • Hardened Steel Backs: The rod bearings come with hardened steel backs that not only support the bearing lining but also help keep everything snug in the housing. No more worrying about slippage!
  • Improved Crush: With increased crush, these bearings stay put, giving you peace of mind when you're revving hard.
  • Heat Transfer: We’ve eliminated flash plating on the backs, which means better heat transfer. This helps maintain grip between the bearings and their housing, especially when things heat up.
  • Increased Eccentricity: This feature helps tackle bore distortion at high RPMs and aids in forming hydrodynamic oil films, crucial for keeping everything lubricated under pressure.
  • 3/4 Grooved Main Bearings: These are designed to optimize load-bearing surface area and oil flow to your conrod bearings, ensuring everything runs smoothly.
  • Tight Wall Tolerances: Consistent wall tolerances mean you can maintain those clearances without a hitch.
  • Enlarged ID Chamfers: For those performance crankshafts with large fillet radii, we’ve got you covered with enlarged ID chamfers on the edges.
