If you’re looking to push your engine to the limit, these ACL Race Series Engine Bearings are worth a serious look. These aren’t your run-of-the-mill bearings; they’re crafted for those who demand durability and performance under high RPM conditions. Whether you’re revving up a 4, 6, or 8-cylinder engine, these bearings have got your back.

What sets them apart?

  • First off, the high-strength overlay plate is thinner than what you might find in regular bearings, which means it handles fatigue like a champ. Less thickness, more resilience.
  • All the rod bearings come with hardened steel backs. This isn’t just for show; it helps keep the bearing lining supported and locked in place, so you don’t have to worry about them moving around when the heat is on.
  • They’ve cranked up the crush for better retention, which means these bearings stay put even when the engine is screaming.
  • Forget about flash plating on the back—these bearings are designed to maximize heat transfer and grip between the bearing and housing. This is crucial when you’re pushing your engine hard.
  • With increased eccentricity, they compensate for any bore distortion at high RPMs. This helps create that all-important hydrodynamic oil film that keeps everything running smoothly.
  • The 3/4 grooved main bearings optimize the load-carrying area and ensure oil flows efficiently to the conrod bearings. It’s all about keeping things lubricated under pressure.
  • They maintain tight wall tolerances for consistent clearances, which is key for performance builds.
  • Plus, they’ve enlarged ID chamfers where needed to fit those beefy fillet radii on performance crankshafts.

Specifications:

  • Size options: STD, .025, .25
  • Oil clearance: Standard
  • Half type: Identical halves
  • Material: Tri-metal with hardened steel backs
  • Min standard shaft size: 1.888 in / 47.956 mm

  • Min standard tunnel size: 2.0079 in / 51.000 mm
  • Max standard tunnel size: 2.0084 in / 51.013 mm
  • Max wall at crown: 0.0592 in / 1.503 mm
  • Max overall length: 0.6732 in / 17.1 mm

Fitment:
