The ACL 4B1912HD-.025 Race Series Engine Bearings are engineered for high-performance applications, making them a must-have for anyone looking to maximize their engine's potential. These bearings are specifically designed to handle the rigors of high RPM conditions, ensuring that your 4, 6, or 8-cylinder engine runs smoothly under pressure.

Fitment

These bearings fit a variety of popular applications, making them an excellent choice for performance builds. Check your specific vehicle compatibility to ensure a perfect fit.

Features

  • High-strength overlay plate with reduced thickness enhances fatigue resistance, allowing you to push your engine harder.
  • Hardened steel backs on all rod bearings improve support for the bearing lining and enhance retention in the housing.
  • Increased crush enhances bearing retention, giving you peace of mind during aggressive driving.
  • Elimination of flash plating on the back improves heat transfer, maximizing grip between the bearings and their housing.
  • Increased eccentricity compensates for bore distortion at high RPM, helping to form hydrodynamic oil films for better lubrication.
  • 3/4 grooved main bearings optimize load-carrying surface area and oil flow to the connecting rod bearings.
  • Tight, consistent wall tolerances maintain precise clearances, crucial for performance engines.
  • Enlarged ID chamfers accommodate large fillet radii on performance crankshafts, ensuring a snug fit.
