ACL High Performance Mini Inline Rod Bearing Set 4B2206H-.001 for 1983 1275cc Engine - 4B2206H-.001

If you're looking to push your engine to its limits, these ACL Race Series Engine Bearings are a solid choice. They’re built for the serious driver who knows that every little detail matters when you’re chasing those higher RPMs. These bearings are designed to hold up under pressure, and trust me, they deliver.

  • The high-strength overlay plate is thinner, which might sound counterintuitive, but it actually enhances fatigue resistance. You want something that can take a beating and keep on going, right?
  • All rod bearings come with hardened steel backs. This isn’t just for show; it helps support the bearing lining and keeps everything snug in the housing.
  • They’ve cranked up the crush for better retention, meaning these bad boys won’t be going anywhere when the engine's revving high.
  • No more flash plating on the back of the bearings. This change boosts heat transfer and maximizes the grip between the bearings and their housing—important when you’re pushing your engine hard.
  • With increased eccentricity, these bearings can handle bore distortion at high RPMs, which helps create those all-important hydrodynamic oil films.
  • The 3/4 grooved main bearings are a game-changer, optimizing load-bearing surface area and ensuring oil flows smoothly to the conrod bearings.
  • They’ve got tight wall tolerances to keep your clearances consistent, which is crucial for performance.
  • And the enlarged ID chamfers? They’re there to accommodate those large fillet radii on performance crankshafts, so you won’t have to worry about fitment issues.

As for specs, these ACL Race Series engine bearings are built for reliability, especially when you’re pushing your engine to its limits. You can get them in sizes: STD, .001, .010. For example, the 4B2206H-.001 is a .001mm oversized high-performance rod bearing set for the 1983 BMC Mini Inline 4 1275cc. Perfect if you’re looking to get every ounce of performance out of that classic engine.

So if you’re ready to take your ride to the next level, these bearings are a no-brainer. They’re tough, reliable, and made for the kind of driving that gets your heart racing.
