King Engine Bearings Toyota 2A/3A/4A/(Size +0.25mm) Connecting Rod Bearing Set

If you're rebuilding the engine in your 1983-1997 Toyota Corolla, especially one with a 2A, 3A, or 4A engine, getting the connecting rod bearings right is crucial for proper oil pressure and smooth operation. These bearings from King Engine Bearings are designed to be a direct replacement for your stock ones, but they come in a 0.25mm undersize to help you achieve the correct clearances if your crankshaft journals have been machined down during a rebuild.

King uses a bimetal construction with an aluminum base for these bearings. This type of material is well-known for its ability to handle the loads and temperatures found in an engine's bottom end, helping to ensure consistent oil film and reduce wear. Because these are a specific undersize, they're intended for use when the crankshaft has been ground down by 0.25mm. Make sure to verify your crankshaft journal measurements before ordering to ensure you get the right fit for your engine build.
