Description

High performance driving demands that you use the best parts. So rely on ACL RACE Series Performance Engine Bearings to perform to the exacting race standards you expect. They provide the dependability it takes to hold up under higher RPM conditions.

The unique combination of design, metallurgy and engineering come together to deliver what drivers expect from high performance parts.

Features and Benefits

Conrod Bearing Features:

  • High performance Trimetal engine bearings
  • Designed to withstand higher RPM conditions
  • High strength overlay plate with reduced thickness for improved fatigue properties

 

ACL Bearing Features:

  • High strength overlay plate with reduced thickness for improved fatigue properties
  • Hardened steel backs on all rod bearings to improve the support of the bearing lining and assist with bearing retention in the housing.
  • Increased crush for improved bearing retention
  • Elimination of flash plating on the back of the bearings to improve heat transfer through the bearings and to maximize the grip between the bearings and its housing.
  • Increased eccentricity to compensate for bore distortion at high rpm and to assist in the formation of hydrodynamic oil films.
  • 3/4 grooved Main Bearings to optimize bearing load carrying surface area and oil flow to the conrod bearings.
  • Tight consistent wall tolerances to help you maintain consistent clearances.
  • Enlarged ID chamfers on bearing edges where required to accommodate large fillet radius on performance crankshafts.
