Product Details

The ACL Bearings 7M7989H-.25 is a high-performance standard main bearing set from ACL's Race Series lineup, designed for demanding engine builds where reliability and durability are paramount. This complete main bearing set features ACL's precision-engineered construction with -.25mm undersize dimensions to accommodate crankshaft journals that have been machined or show wear.

Key Features:

  • Race Series construction for high-performance and racing applications
  • -.25mm undersize specification for machined or worn crankshaft journals
  • Tri-metal bearing construction with high-strength steel backing
  • Precision tolerances for optimal oil clearance and bearing life
  • Enhanced fatigue resistance for extreme operating conditions
  • Complete main bearing set for full engine rebuild coverage

ACL Race Series bearings are manufactured to exacting standards and incorporate advanced materials and coatings to withstand the rigors of high-RPM operation, increased cylinder pressures, and extended racing duty cycles. The undersize specification allows machinists to restore proper bearing clearances when rebuilding engines with journals that have been ground undersize during crankshaft reconditioning.
