    Crankshaft Main Bearing Kit for Infiniti/Nissan Engines

    Keep your bottom end tight and smooth. This OEM-grade main bearing set supports the crankshaft, controls oil clearance, and cuts friction for quiet running and stable oil pressure. Ideal for engine rebuilds or a bottom-end refresh when restoring factory smoothness and durability.

    Why this part is needed ️

    Bearings center the crank in the block and create the thin oil film that carries load. Correct clearance prevents metal-to-metal contact, keeps temperatures down, and protects journals during high RPM and hot starts.

    How it works

    Precision shells with tri-metal layers cradle each main journal. Pressurized oil feeds grooves and holes, forming a hydrodynamic wedge. With the right micrometer-level tolerance, the crank floats on oil for low wear and consistent pressure.

    What happens if worn or broken ⚠️

    Cold-start knock, low oil pressure light, glitter in oil, harsh vibration, and bearing noise. Continued driving risks spun bearings, seized crank, damaged journals, and even connecting-rod failure—often terminal for the engine.

    Pro tips for install

    Measure journals and housings, select correct grades, clean oil passages, use assembly lube, torque in sequence, and verify with Plastigage. Check thrust clearance and replace related fasteners and seals.
