Product Details

The King Engine Bearings MB763SI main bearing set is engineered specifically for AMC and Jeep inline-six engines, including the 199, 232, 242, and 258 cubic inch models. This complete main bearing set provides the precision and durability needed for engine rebuilds and performance applications.

Key Features:

  • Bi-metal construction with silicon aluminum alloy for enhanced strength and wear resistance
  • Aluminum-based material reinforced with 2.5-3% silicon content
  • Optimized for medium load applications and nodular cast iron crankshafts
  • Precision manufactured to OEM specifications for proper fitment
  • Complete main bearing set for full engine rebuild coverage

King Engine Bearings are a trusted choice among engine builders and automotive professionals for their consistent quality and performance. The silicon-aluminum alloy provides excellent bearing characteristics including improved seizure resistance, better embedability of foreign particles, and superior conformability to slight crankshaft imperfections.
