What is the construction of these main bearings?

These main bearings are made with a bimetal construction that uses an aluminum base. This type of material helps with heat dissipation and wear resistance in the critical areas where the crankshaft rotates.

Are these bearings a direct replacement for the original equipment?

Yes, these are standard size main bearings designed as a direct replacement for the specified Datsun L18 engines in the listed Nissan vehicle applications.

What does 'STD' mean for the size?

STD refers to 'standard' size. This means the bearings are manufactured to the original equipment manufacturer's specifications and are intended for use when the crankshaft journals are not worn beyond their service limits and do not require an undersize bearing.

Product Details

This is a standard size main bearing set from King Engine Bearings, designed for Datsun L18 engines. You get the main bearings needed to rebuild or replace the crankshaft bearings in your engine. These bearings feature a bimetal construction with an aluminum base, which helps manage heat and wear in the critical areas where the crankshaft rotates.

Using a well-built bearing set like this is important for ensuring proper oil clearance and supporting the crankshaft under load, which is key to a healthy engine rebuild.
