If you're diving into the world of serious performance upgrades, you’ve probably heard about ACL Race Series Engine Bearings. These aren't just any bearings; they’re built for the kind of drivers who push their engines to the limit. Made with a unique blend of design, metallurgy, and engineering, these bearings are engineered to handle higher RPMs without flinching.

Here’s what makes these bearings stand out:

  • High Strength Overlay: The overlay plate is thinner but packs a punch when it comes to fatigue resistance. You won't have to worry about them giving out under pressure.
  • Hardened Steel Backs: Every rod bearing features hardened steel backs, which really helps support the bearing lining and keeps it snug in the housing. This is crucial for those high-stress situations.
  • Increased Crush: The crush is beefed up, which means better retention of the bearings where they belong.
  • No Flash Plating: By ditching the flash plating on the back, heat transfer improves significantly. This means better grip between the bearings and their housing, which is vital for performance.
  • Increased Eccentricity: This feature compensates for any bore distortion you might experience at high RPMs and helps form those all-important hydrodynamic oil films.
  • 3/4 Grooved Main Bearings: They optimize the load-carrying surface area and enhance oil flow to the conrod bearings, ensuring everything stays lubricated under pressure.
  • Tight Wall Tolerances: Consistency is key, and these bearings help you maintain those clearances you need for a smooth ride.
  • Enlarged ID Chamfers: These are designed where needed to fit those larger fillet radii on performance crankshafts, so you won’t run into any surprises during installation.

Now, let's get into the nitty-gritty specs:

  • Size: STD
  • Oil Clearance: +0.001" Extra
  • Half Type: Identical Halves
  • Material: Tri-metal with hardened steel backs
  • Min Std Shaft Size: 2.0860" / 52.984mm
  • Max Std Shaft Size: 2.0867" / 53.002mm
  • Min Std Tunnel Size: 2.2388" / 56.866mm
  • Max Std Tunnel Size: 2.2396" / 56.886mm
  • Max Wall at Crown: Std: 0.0754" / 1.915mm
  • Max Overall Length: 0.825" / 20.96mm

For those running a Ford 4.6L or 5.4L V8, this is the set you want in your corner. These bearings are built to last and help you get the most out of your engine. Trust me, when you’re pushing the limits, you want bearings that are up for the challenge.
