What does 0.50mm undersize mean for these bearings?

This means the bearings are manufactured to be 0.50mm smaller in diameter than the standard size. This is typically used when the engine's crankshaft journals have been machined down (ground) to remove imperfections or wear, and you need a bearing that matches the new, smaller journal diameter.

What is the construction of these bearings?

These bearings feature a bimetal construction, which uses an aluminum base. This design is known for its good load-carrying capabilities and durability in engine applications.

Are these bearings a direct replacement for all 4A engines?

These bearings are specifically designed for Toyota 2A, 3A, and 4A engines and are 0.50mm undersize. Always confirm your specific engine code and crankshaft condition to ensure this size is appropriate for your rebuild.

About this part

Product Details

When you're rebuilding the bottom end of your 1983-1997 Toyota Corolla with a 2A, 3A, or 4A engine, a fresh set of connecting rod bearings is essential. This set from King Engine Bearings is built with a bimetal construction, meaning it has an aluminum base for good load-carrying capacity and durability. These bearings are also 0.50mm undersize, which is important if you've had your crankshaft ground down during the rebuild process.

King Engine Bearings is a well-known name in engine components, and this set is designed to fit right into your Toyota's connecting rods. The aluminum base offers a solid foundation for the bearing surface, helping to manage the forces generated during engine operation. Having the correct size bearings is critical for proper oil clearance, which ensures your engine runs smoothly and lasts.
