Why Choose ACL Race Series Engine Bearings?

ACL’s unique combination of design, metallurgy, and engineering delivers performance that meets the demands of high-stress driving conditions. Here’s what sets these bearings apart:

  • Hardened steel backs on all rod bearings improve support for the bearing lining and assist with secure retention in the housing.
  • Increased crush enhances bearing retention, providing a more stable fit.
  • Elimination of flash plating on the back of the bearings maximizes heat transfer and grip between the bearings and their housing.
  • Increased eccentricity compensates for bore distortion at high RPM, promoting the formation of hydrodynamic oil films.
  • 3/4 grooved main bearings optimize load carrying surface area and oil flow to the conrod bearings.
  • Tight, consistent wall tolerances help maintain precise clearances essential for performance.
  • Enlarged ID chamfers accommodate larger fillet radii on performance crankshafts, ensuring a perfect fit.
