King Engine Bearings MB 534AM0.75 OE Replacement Main Bearing Set 0.75mm Undersize

The King Engine Bearings MB 534AM0.75 is an OE-replacement crankshaft main bearing set designed for the Datsun/Nissan L18 engine. This set includes 5 pairs of bi-metal aluminum main bearings machined to a 0.75mm undersize, making it the correct choice for engines with reground or worn crankshafts requiring the 0.75mm journal size.

Key Features:

• AM-Series Bi-Metal Construction: Utilizes King's standard aluminum-based material (equivalent to SAE-783), the softest bi-metal in King's lineup — ideal for passenger car engines with low to medium loads
• 100% Lead-Free: Environmentally safe, lead-free aluminum composite material for safer handling and disposal
• Bull's Eye Tolerance™ Technology: Combines precision machining, overplating, and computerized wall thickness monitoring for exceptional dimensional accuracy
• 0.75mm Undersize: Engineered for crankshafts that have been ground 0.75mm under standard journal diameter
• Superior Embeddability: Aluminum bi-metal construction provides excellent macro-particle embeddability, helping protect crankshaft journals from wear and damage
