King Engine Bearings Datsun J15/(Size +0.75mm) Main Bearing Set

Built with an aluminum base, this main bearing set from King Engine Bearings is specifically made for Datsun J15 engines.

The bimetal construction helps manage heat and wear, crucial for the longevity of your engine's rotating assembly.

When you're rebuilding an engine, the main bearings are a critical component. They support the crankshaft and allow it to spin smoothly within the engine block. Using a well-built set like these from King Engine Bearings ensures that your J15 engine has the proper support it needs. The 0.75mm oversize is a specific measurement that needs to match the machined size of your crankshaft journals for a correct fit and optimal oil clearance.
