Product Details

The King Engine Bearings MB5540AM0.25 is an OE-replacement bi-metal main bearing set designed for the Isuzu 4XC1/T and 4XE1W engines. This +0.25mm oversize set is engineered to restore proper crankshaft clearances during engine rebuilds where the crank journals have been machined undersize.

AM Series — Aluminum Bi-Metal Construction:

  • Bi-metal aluminum-based material equivalent to SAE-783 specification
  • King's softest bi-metal formulation — optimized for passenger car engines operating under low to medium loads
  • Provides excellent conformability and embeddability to accommodate minor surface imperfections
  • Steel backing for structural rigidity and reliable housing fit
  • Precision-manufactured to King's tight wall thickness tolerances for consistent oil film clearance
  • Complete set includes 5 pairs of main bearings

The King AM Series is an ideal choice for OE-replacement engine rebuilding. Employing King's standard aluminum-based bi-metal material, these bearings deliver dependable performance and long service life in stock or mildly modified engines. King Engine Bearings has been manufacturing precision engine bearings since 1960, supplying both OEM and aftermarket customers worldwide.

Boom baby!!!

Found exactly what I was looking for and for a good price. The checkout is nice and simple and easy to use. However, when I sent them an email before my order shipped saying that I need to have one item removed from the order, I never got an answer and my

Great transaction

So far so good

Great company to do business with! Ordered a Thule 916XTR bike rack for my car and their prices blew away everyone else on the 'net! Ordered on Sunday, they shipped on Monday and sent me a tracking number that night. Super fast shipping and great communication! I'll definitely be coming back to Autoplicity again!

good

Good so far

Best price on Bilstein Shocks on the web. Ordered shocks on 4/25 and they shipped same day. FedEx has delivery date of 4/28. Received confirmation email after order was complete. Website had product inventory next to part number was very helpful. Other websites don't have this and this patprticular part is on back order for 30 + days. Will update once shipment received.

I can't believe how much money I saved buying from Autoplicity. I had been shopping the Bakflip for months and this price easily beat every other online store for the same exact item. My item shipped direct from the factory within days. I couldn't be happier.
