Product Details

The King Engine Bearings MB5557SI0.75 is a precision-engineered main bearing set designed specifically for Chevrolet 121 cubic inch and LN2 134 cubic inch engines. This complete main bearing set provides reliable crankshaft support for engine rebuilds and performance applications.

Key Features:

  • Bi-metal silicon aluminum construction for optimal strength and durability
  • Aluminum-based material reinforced with 2.5-3% silicon content
  • Engineered for medium load engines and nodular cast iron crankshafts
  • 0.75mm oversize for worn or machined crankshaft journals
  • Precision manufacturing ensures proper oil clearances and bearing crush
  • Direct replacement for Chevrolet small displacement engines

The silicon-aluminum alloy composition provides excellent wear resistance and conformability, making these bearings ideal for street performance and moderate duty applications. The 0.75mm oversize allows for proper fitting on crankshafts that have been ground to restore journal surfaces. King Engine Bearings are trusted by engine builders worldwide for their quality and precision tolerances.
