  • Tri-metal construction with hardened steel backing, copper-lead intermediate layer, and polymer overlay
  • Enhanced oil retention grooves for improved lubrication and reduced friction
  • Precision bore geometry ensures optimal clearances and consistent oil film thickness
  • Engineered for high-load applications including racing, turbo, and supercharged engines
  • Complete connecting rod bearing set for one engine rebuild

ACL bearings meet or exceed OEM specifications while offering improved performance characteristics.
