Product Details

The King Engine Bearings MB7039AM0.25 is an OE-replacement crankshaft main bearing set designed for BMW and Opel diesel engines including the M51, M57, D25, and Y25 TD. This set features a +0.25mm undersize specification, making it the correct choice for engines with cranks that have been reground to the first oversize.

Constructed using King's bi-metal aluminum-based material — the softest alloy in King's bearing lineup — this bearing is equivalent to SAE-783 and engineered for low to medium load passenger car engine applications. The lead-free aluminum composite offers an environmentally sound alternative while delivering consistent performance and reliable oil film retention throughout the bearing's service life.

Key Features:

  • OE Replacement grade — direct-fit substitute for factory main bearings
  • Bi-metal construction with aluminum-based overlay, equivalent to SAE-783 specification
  • +0.25mm undersize for use with reground crankshafts
  • Lead-free material — environmentally safe composite formulation
  • Set includes 7 pairs of main bearing shells
  • Manufactured in Israel to King's strict quality control standards
  • Compatible with BMW/Opel M51, M57, D25, and Y25 TD engine families

King Engine Bearings has specialized exclusively in engine bearings since 1960, supplying OE-quality and performance bearings for automotive, truck, marine, aviation, and power generation applications worldwide. The AM Series is the ideal choice for stock rebuilds and daily-driven engines requiring a reliable, cost-effective OE-style replacement.

Great experience with autoplicity. Fast shipping. Ordered on 5/31 got bed cover on 6/2. Fit truck perfect.

smooth transaction. good seller.

Shopping was fast and easy. The paint was the cheapest on Google search.

Great price. Easy transaction.

Web interface seems a little clunky-----a lot of seemingly unnecessary scrolling.

The kit I needed was available at the best price on Autoplicity. I asked a question by live chat. It was a slow response, but once my question was forwarded to the appropriate source, the response was quick, helpful and professional.

I was very pleased with the price of the part and expediency with which the order was processed. I will definitely consider buying from them again.
