If you’re looking to give your engine a serious upgrade, let me tell you about these ACL Race Series Engine Bearings. They’ve got a solid rep among those of us who push our rides to the limit. These aren’t just any bearings; they’re designed to handle the heat and stress of high RPMs without breaking a sweat. Perfect for those who love to rev it up, whether you’re in a 4, 6, or 8-cylinder setup.

What makes these bearings stand out?

  • First off, the high-strength overlay plate is thinner, which means better fatigue resistance. That’s crucial when you’re pushing your engine hard.
  • Then there’s the hardened steel backs on all rod bearings. This helps keep the lining in place and ensures they hold up under pressure.
  • They’ve increased the crush to improve retention—no one wants to worry about bearings shifting when you’re hitting the track.
  • Say goodbye to flash plating on the back. This change enhances heat transfer and improves the grip between the bearings and the housing. It’s all about keeping things cool and steady.
  • With increased eccentricity, these bearings can handle bore distortion at high RPMs while helping to form those all-important hydrodynamic oil films.
  • The 3/4 grooved main bearings are a game-changer, optimizing the load-carrying surface area and oil flow to the conrod bearings.
  • And let’s not forget the tight, consistent wall tolerances, which help maintain those all-important clearances.
  • Finally, the enlarged ID chamfers on the edges accommodate large fillet radii on performance crankshafts—no more worrying about fitment issues.

Here’s the nitty-gritty:

  • Sizes available: STD, 025, .25
  • Oil Clearance: Standard
  • Half Type: Identical Halves
  • Material: Tri-metal Hardened Steel Backs
  • Min Std Shaft Size: 1.889in / 47.98mm
  • Max Std Shaft Size: 1.8898in / 48 mm
  • Min Std Tunnel Size: 2.008in / 51.004mm
  • Max Std Tunnel Size: 2.0088in / 51.024 mm
  • Max Wall at Crown: 0.0589in / 1.496 mm
  • Max Overall Length: 0.7638in / 19.4mm

Fitment: These bearings are a perfect match for the Honda S2000 from 2000 to 2009, specifically for the F20C/F22C and H22A4 engines. The 0.025mm oversized option gives you that extra edge you need for high performance—ideal for those who really push their machines.

So if you’re serious about your engine’s performance, these ACL bearings are a solid choice. They’re built to last and handle whatever you throw at them. Trust me, your engine will thank you.
