Product Details

The King Engine Bearings MB5514AM is an AM-Series crankshaft main bearing set designed for OE replacement on Oldsmobile 260, 307, 330, 350, and 403 cubic inch engines.

Constructed using King's standard aluminum-based bi-metal (Alecular silicon) material, the AM-Series is the softest bi-metal in King's lineup and is equivalent to SAE-783. This material provides excellent conformability and embeddability, allowing the bearing to absorb microscopic debris and protect crankshaft journals from scratching and wear.

Key Features:

  • AM-Series bi-metal construction with aluminum-based (Alecular silicon) material
  • Full groove design — upper and lower bearings both grooved for consistent oil flow
  • Standard (stock) crankshaft undersize and thrust bearing oversize
  • Tolerance control to within ±0.0001 inches for precision fitment
  • Lead-free construction — environmentally friendly and user safe
  • Superior embeddability reduces macro-particle scratching of crank journals
  • Recommended for street and marine engine rebuilding applications

King Engine Bearings has specialized exclusively in engine bearings since 1960, manufacturing every bearing in-house and subjecting each set to rigorous quality control checkpoints. The MB5514AM is the trusted OE-replacement choice for Oldsmobile engine rebuilds requiring a dependable, precision-fit main bearing set.

this is my new home... very cool site, beat summit and jegs by $20 to $30

Great customer service. Fast order processing. Hassle free transaction.

Very fast shipping, received it Monday when I ordered it on Thursday. Thanks!

Great price and fast shipping! If your looking for quality brands at the best price available!!<br>

I found my part easily (vent visors), checkout was simple, and I was notified the very next day that my item has been sent. The price (including shipping) was way lower than anywhere else online or in town.

Autoplicity is awsome!! lowest prices.. fast shipping great customer service.. this is hard to find in todays world!!

Great service and communication. Once it was shipped, I was able to track my item. Best price I could find on the internet!! Would definitely do business with anytime.

Fantastic ! Ordered a Weather Tech Cargo Liner for my 2012 Ford Explorer. Price was $60 less here than ALL other sites on web. I was skeptical that this was going to be a counterfeit -- as the price was too good to be true. I was extremely happy to receive the genuine product as I expected in less than a week -- and for $60 less than the competitors ! GREAT VALUE and great service ! I will definitely be back !!

Couldn't be more happy with my product. I ordered from Autoplicity because they were the cheapest price around and I received my order within 5 days. I have installed the cold air intake and couldn't believe all the extra power. I am very pleased with the entire transaction.
