ACL Toyota 3TC P-Series 0.30 Oversized Rod Bearing Set - High Performance Trimetal Bearings - 4B1686P-30

If you're looking to push your engine to the limit, these ACL Race Series Engine Bearings are where it’s at. Seriously, they’re built for those of us who crave high performance and know what it takes to keep our engines running smoothly at high RPMs. Whether you've got a 4, 6, or 8-cylinder setup, these bearings are designed to take the heat and keep your ride in the game.

What makes them special?

  • First off, the overlay plate is tough but slim. This reduced thickness means better fatigue properties, which is crucial when you're revving high.
  • All the 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, so you don’t have to worry about them moving around.
  • They’ve cranked up the crush for better bearing retention. That means they stay put where they belong, even when the engine is screaming.
  • No flash plating here! This design choice improves heat transfer and maximizes grip between the bearings and their housing, which is vital for high-performance applications.
  • Plus, there's increased eccentricity to handle any bore distortion at those high RPMs, helping to create hydrodynamic oil films. Trust me, that’s a game changer.
  • The 3/4 grooved main bearings are a nice touch, optimizing the load-carrying surface area and ensuring oil flows smoothly to the conrod bearings.
  • And let’s not forget the tight wall tolerances. This helps you maintain consistent clearances, which is key when you're pushing your engine hard.
  • Lastly, the enlarged ID chamfers on the edges make sure they fit nicely with performance crankshafts that have larger fillet radii.

For those working on a Toyota 3TC, the 4B1686P-30 set is a 0.30 oversized rod bearing set that fits like a glove. If you're serious about your build and want to keep things running smoothly under pressure, these bearings are a solid choice. They’re not just parts; they’re a step towards making your engine perform the way you want it to.
