Product Details

The King Engine Bearings MB5243AM1.0 is a main bearing set designed for Nissan SR20DE engines. Manufactured with King's bi-metal aluminum construction, this bearing set meets SAE-783 material standards, making it well-suited for low to medium load engine applications.

Key Features:

  • Material: Bi-Metal Aluminum — standard aluminum-based construction equivalent to SAE-783
  • Application: Designed for the Nissan SR20DE engine platform
  • Size: 1.0mm oversized (indicated by the AM1.0 suffix), suitable for re-ground or worn crankshafts
  • Consistent wall thickness for reliable oil film maintenance and reduced engine wear
  • Precision manufacturing to tight tolerances for proper clearance and long service life

King Engine Bearings are an OEM-quality solution trusted by engine builders worldwide. The bi-metal aluminum compound provides dependable performance in street and light-performance SR20DE applications. The 1.0mm oversize specification makes this set ideal for engine rebuilds where the crankshaft has been re-ground to restore proper journal geometry.
