Product Details

The King Engine Bearings MB517SI040 is a complete crankshaft main bearing set designed for the Chrysler 360 cubic inch V8 engine. This set is machined to a 0.040" undersize journal diameter, making it the ideal choice for engines that have had the crankshaft reground to restore worn main journal surfaces.

Constructed using King's SI bi-metal material, the bearing shells feature an aluminum-silicon alloy running surface — a lead-free compound that blends aluminum with 2.5–3% silicon for enhanced strength and durability. This material is specifically engineered for medium-load engines, particularly those equipped with nodular cast iron crankshafts, and serves as a direct OE-replacement bearing solution without the use of hazardous lead compounds.

Key Features:

  • SI Bi-Metal Construction: Lead-free aluminum-silicon alloy bonded to a steel backing for a reliable, environmentally responsible OE replacement
  • 0.040" Undersize: Designed for crankshafts that have been reground 0.040" under standard journal diameter
  • 5 Pairs Included: Complete main bearing set covering all five main journal positions for the Chrysler 360 V8
  • Bull's Eye Tolerance™ Technology: King's proprietary manufacturing process combines precision machining, overplating, and computerized wall thickness monitoring to maintain shell-to-shell consistency far tighter than industry standard
  • Crankshaft Shaft Diameter: 2.8095" – 2.8105" (71.361–71.387mm)
  • Housing/Tunnel Diameter: 3.0025" – 3.0030" (76.264–76.276mm)
  • Lead-Free Formula: Prioritizes environmental sustainability without sacrificing performance in medium-load street and performance applications

King Engine Bearings has specialized exclusively in engine bearings since 1960, applying knowledge gained from aviation and motorsport applications to every bearing in their catalog. The MB517SI040 delivers consistent fitment and reliable crankshaft support for rebuilt Chrysler 360 engines requiring a 0.040" undersize main bearing set.

Arrived in good working order.

Excellent service and fast shipping. A seller I would do business with again.

I ordered an AEM intake for my F-150 on Christmas day and received it on the 29th. I would absolutely recommend this site to anyone looking for car parts - they had the lowest price by far and shipped fast. Great job!

was fast

very good low price, had a slight issue but customer service was amazing,. i would recommend AutoPlicity to anyone because of that, good prices, good customer service,. (meaning trust worthy) why not :). A+++ Service will buy from again!

Great price and quick shipping!

Lowest price on the Internet, good packaging and fast shipping.

Excellent service!!!! Ordered another part from one of those big chain stores three days earlier and got your part one day sooner than theirs. Thanks. Excellent customer service. Wouldn't hesitate to use you again.

Great product and speedy service!

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.
