King Engine Bearings Toyota 18R/(Size +0.50mm) Main Bearing Set

King Engine Bearings is well-known for making solid engine components. If you're rebuilding the bottom end of your 1967-1974 Toyota Corona, these main bearings are a key part of that job. They sit between your crankshaft and the engine block, allowing the crank to spin smoothly while supporting the weight of the rotating assembly.

This set is built with a bimetal construction, using an aluminum base. This type of bearing is chosen for its ability to handle the loads and temperatures inside an engine. Since these are a 0.50mm undersize set, they are intended for use when the crankshaft journals have been machined down by that amount to clean up wear or damage. Using the correct undersize bearing ensures a proper fit and oil clearance, which is critical for engine longevity.
