Alright, let’s talk about the ACL Race Series Engine Bearings. If you’re pushing your engine to the limit—whether it's on the track or just getting some serious pedal time on the street—these bearings are built to handle the heat. They’re not just your average bearings; they’re designed with a unique blend of metallurgy and engineering that really sets them apart.

One of the standout features is the high-strength overlay plate, which is thinner than what you might find in standard bearings. This isn’t just for show; it actually improves fatigue properties, making them more durable under high RPM conditions. Plus, all the rod bearings come with hardened steel backs. This means better support for the lining and helps keep everything locked in place in the housing. Trust me, you don’t want your bearings moving around when you're revving high.

These bearings also have increased crush, which helps with retention. You won’t have to worry about them slipping out of place. And they’ve eliminated flash plating on the back, which means better heat transfer. This little tweak maximizes the grip between the bearings and their housing, ensuring you get the most out of your setup.

When it comes to high RPM performance, the increased eccentricity is a game changer. It compensates for any bore distortion you might encounter, helping to form those all-important hydrodynamic oil films. And if you're running a performance crankshaft, the enlarged ID chamfers on the bearing edges are designed to accommodate larger fillet radii, so you won’t run into clearance issues.

Now, let’s get into the nitty-gritty specifications:

  • Size: STD
  • Oil Clearance: +0.001" Extra
  • Half Type: Identical Halves
  • Material: Tri-metal Hardened Steel Backs
  • Min Std Shaft Size: 1.7709in / 44.98 mm
  • Max Std Shaft Size: 1.7717in / 45 mm
  • Min Std Tunnel Size: 1.8898in / 48 mm
  • Max Std Tunnel Size: 1.8898in / 48 mm
  • Max Wall at Crown: 0.0587in / 1.491 mm
  • Max Overall Length: 0.7677in / 19.5 mm

These bearings fit a range of Honda models, including:

  • Honda Accord (1986-2020)
  • Honda Prelude (1983-2001)

For those running the B18A1/B18B1 engines, this Race Series Rod Bearing Set (part number 4B1946HXD-STD) is a solid choice. If you’re serious about performance and want something that can handle the demands of your engine, these bearings are definitely worth considering.
