This standard size bearing set features ACL's H-Series construction with extra clearance (HX) design, providing an additional .001" oil clearance compared to standard H-Series bearings for high-performance and racing applications.

Key Features:

  • Multi-layered tri-metal copper alloy construction for high strength and excellent seizure resistance
  • HX-Series designation provides .001" (.025mm) extra oil clearance for performance builds
  • Manufactured to exact tolerances ensuring reliable fit and consistent clearances
  • Extended oil grooves for enhanced lubrication
  • Increased crush, bearing eccentricity, and enlarged I.D. chamfers
  • Standard size bearings for use with factory crankshaft journals
  • Complete main bearing set for Ford 429-460 big block engines

ACL Race Series bearings are proven in championship-winning engines across NASCAR, IHRA, and NHRA competition. The extra clearance design makes this set ideal for performance street builds, racing applications, and engine combinations requiring additional oil flow. Made in Australia with precision quality control and decades of bearing engineering expertise.
