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

These connecting rod bearings are built with a bimetal construction, featuring an aluminum base. This design is intended for the Toyota 3K and 4K engines, commonly found in the 1968-1979 Toyota Corolla and also fitting the 1981-1984 Toyota Starlet. They are specifically sized at 0.25mm undersize, which is important when rebuilding or servicing an engine that may have had previous machining work done on the crankshaft journals.

King Engine Bearings uses this aluminum-based bimetal material to help manage heat and provide a solid foundation for the bearing surface. When you're putting an engine back together, especially one from this era, ensuring the connecting rod bearings are in good shape is critical for proper oil pressure and the longevity of your engine's rotating assembly. These bearings are designed to fit right into place, making them a straightforward component for your engine rebuild.
