ACL Toyota 4 1762cc 7AFE .50mm Oversized Rod Bearing Set 1993-1997 Trimetal Engine Bearings - 4B1680A-.5

Hey there, fellow gearheads! If you're looking to give your engine the kind of bearings it deserves, let me tell you about the ACL Race Series Engine Bearings. These aren't just any bearings; they're crafted for serious performance. Designed specifically for those high-RPM conditions that make your heart race, these Trimetal bearings are perfect for 4, 6, and 8-cylinder setups. Whether you're building a daily driver or a weekend warrior, these bearings have got your back.

What Makes Them Stand Out?

  • High-Strength Overlay: The reduced thickness of the overlay plate means better fatigue resistance. You want your bearings to take the heat, and these do just that.
  • Hardened Steel Backs: All the rod bearings feature hardened steel backs. This not only supports the bearing lining but also keeps them snug in their housing—no slipping around when you’re pushing the limits.
  • Increased Crush: More crush means better bearing retention. You want these babies to stay put, especially when the engine's screaming at high RPMs.
  • No Flash Plating: We’ve eliminated flash plating on the back. This helps with heat transfer and maximizes grip between the bearings and housing. It’s all about keeping things cool and secure.
  • Increased Eccentricity: This feature compensates for bore distortion at high RPMs, which is crucial for forming those hydrodynamic oil films that keep everything running smoothly.
  • 3/4 Grooved Main Bearings: These are designed to optimize load carrying and oil flow to the conrod bearings. More oil where you need it means better performance.
  • Tight Wall Tolerances: You’ll appreciate the consistent clearances. It makes a difference when you're tuning for performance.
  • Enlarged ID Chamfers: This is for those of you running performance crankshafts with large fillet radii. It’s all about making sure everything fits just right.
