Product Details

The King Engine Bearings MB 770AM0.75 is a complete main bearing set engineered for BMW M30-series inline-six engines, including the M30B25, M30B28, M30B32, M30B33, and M30B35 variants. This set is offered in a 0.75mm undersize to accommodate crankshafts that have been reground during engine rebuilding.

Material Construction:

  • Bi-Metal Aluminum (SAE-783 equivalent) — a standard aluminum-based bearing material designed for low to medium load applications
  • Aluminum overlay provides excellent conformability and embeddability, helping the bearing seat properly and tolerate minor surface irregularities
  • Bi-metal construction offers a reliable balance of strength and wear resistance suitable for street and mild performance rebuilds

Key Features:

  • 0.75mm undersize for use with reground or undersized crankshafts
  • Precision-manufactured to OEM tolerances for consistent oil clearance
  • Compatible with BMW M30-series inline-six engines spanning multiple displacement variants
  • King's tight dimensional control ensures proper crush and oil film maintenance

King Engine Bearings is a globally recognized manufacturer of precision engine bearings, supplying both OEM and aftermarket channels. The MB 770AM0.75 set is an ideal choice for professional engine builders and enthusiasts performing a thorough rebuild of the BMW M30 powerplant.
