ACL Race Series Engine Bearings - 6B1584H-STD

If you're looking to push your engine's limits, the ACL Race Series Engine Bearings (6B1584H-STD) are engineered specifically for high-performance applications. These bearings are designed to handle the demands of higher RPMs, making them a perfect choice for enthusiasts who want to get the most out of their 4, 6, or 8-cylinder engines.

Fitment

These bearings fit a wide range of popular applications, ensuring that you can find the right match for your vehicle. Always confirm compatibility based on your specific year, make, and model to achieve optimal performance.

Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance, allowing for better performance under stress.
  • Hardened steel backs on all rod bearings provide superior support for the bearing lining, ensuring they stay securely in place within the housing.
  • Increased crush enhances bearing retention, reducing the risk of failure during high-load conditions.
  • Flash plating elimination on the back of the bearings improves heat transfer, maximizing grip between the bearing and housing.
  • Increased eccentricity compensates for bore distortion at high RPMs, promoting the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings optimize the load-carrying surface area and enhance oil flow to the conrod bearings.
  • Tight, consistent wall tolerances help maintain precise clearances, crucial for performance builds.
  • Enlarged ID chamfers on bearing edges accommodate large fillet radii on performance crankshafts, ensuring a perfect fit.

Specifications

  • Size Options: STD, .025, .25
