Product Details

The King Engine Bearings MB 553AM1.25 is an AM-Series oversize main bearing set engineered for the Datsun A12 engine. This set is sized +1.25mm oversize, making it the correct choice during engine rebuilds where crankshaft journals have been ground undersize to restore proper tolerances.

King's AM-Series bearings are constructed from a tri-metal, aluminum-based bimetal material equivalent to SAE-783, offering an excellent balance of embedability, wear resistance, and fatigue strength. The aluminum alloy composition delivers superior performance in low- to medium-load street and marine engine applications, and the lead-free construction makes these bearings both environmentally responsible and safe to handle.

Key Features:

  • AM-Series tri-metal aluminum-based bearing material (SAE-783 equivalent)
  • +1.25mm oversize for use with reground crankshaft journals
  • Superior embedability to protect crank journals from macro-particle damage
  • Lead-free construction — environmentally friendly and user-safe
  • Precision tolerance control to ±0.0001 inch for consistent oil clearance
  • Full main bearing set included for complete engine rebuild

King Engine Bearings has been a trusted name in engine bearing manufacturing since 1960, producing precision bearings for automotive, light- and heavy-duty truck, marine, aviation, and standby power applications. Every bearing is manufactured to the highest material and design standards for long-lasting engine protection.

Best price. Received confirmation of shipment two days after placing order. Hoping to see product soon.

Pretty easy

So far so good haven't got it in the mail yet

Autoplicity is a great merchant to do business with. They stock a wide variety of high performance parts at rock-bottom prices, and they ship quickly without any hassles. They are a pleasure to deal with.

fast , e-z , great price

Great price on product sold out at my "regular" place. My only negative was that I didn't get info to track the package or know when it would be delivered -- until AFTER it had been delivered. But that's not such a bad thing; it was a nice surprise when it showed up! I'll be recommending you to friends.

easy checkout

I felt I had to double check with Centric site as your brake shoe compatiblity chart didn't seem to go past 1956.

very quick and easy

Best price shipped on my product period. MBRP light bar for my Wrangler JK. Product shipped day after order was placed and arrived 2 business days later. Product was as advertised. Best price, fast service= return customer. Thanks

What a great find! These people are very helpful and their prices are better than 4 wheel parts! The only thing I wish was improved was the handling time to be less than 4 days for 1 item, but other than that, I'm happy.

best price i can find. shipping scheduled only 4days after i order. haven't received it but looks fast.

This was my first time placing an order with Autoplicity and I would not hesitate to order from them again. The product was as described and shipping was very fast, received the item in 2 days. Good price too! Thanks Autoplicity.
