Product Details

The King Engine Bearings MB7776SI0.5 is a precision-engineered main bearing set designed specifically for BMW N55 B30A, N53 B30A, and N52 B30A inline-6 engines. This oversize bearing set features a +0.50mm (0.020") sizing to accommodate machined crankshafts during engine rebuilds and performance builds.

Key Features:

  • Bimetal construction with aluminum-silicon alloy base for superior strength and heat dissipation
  • Precision tolerances for optimal oil clearance and crankshaft support
  • Oversize +0.50mm design for use with reground or undersized crankshafts
  • OEM-quality materials engineered for high-performance and racing applications
  • Direct replacement for BMW engine rebuilds requiring oversize bearings

The aluminum-silicon bimetal construction provides excellent wear resistance, conformability, and embedability while maintaining structural integrity under high loads and temperatures typical of modern turbocharged BMW engines.

Excellent business. This is my second purchase and there will be more! I ordered my parts over the holiday weekend and they mailed them the Tuesday after Labor Day. The absolute BEST pricing you will get. You will not find a lower price else ware. The shipping doesn't even take forever like most places you get great pricing. Communication is excellent, the site is very easy to use and navigate. I will be doing business with Autoplicity.com many more times and highly recommend them.
