Product Details

If you're rebuilding the bottom end of your 1968-1979 Toyota Corolla with a 3K or 4K engine, a fresh set of main bearings is crucial. These bearings sit between your crankshaft and the engine block, supporting the rotating assembly and ensuring smooth operation. This set from King Engine Bearings is specifically sized at 0.25mm undersize, which is important if your crankshaft journals have been machined down during a rebuild.

King uses a bimetal construction with an aluminum base for these main bearings. This design helps manage heat and wear effectively in your engine. Because they are a direct replacement for the original equipment, they are designed to fit right into your existing block and crankshaft setup, making the installation process more straightforward when you're putting your engine back together.
