Product Details

The King Engine Bearings MB557XPC is a high-performance main bearing set designed for General Motors small block V8 engines, including 262, 267, 302, 307, 327, and 350 cubic inch displacements. This professional-grade bearing set is part of King's Performance Series racing line, engineered to deliver superior durability and reduced friction in demanding applications.

Key Features:

  • pMaxKote polymer coating for enhanced wear resistance and break-in protection
  • Precision-engineered bearing surfaces for optimal oil clearance and film strength
  • Tri-metal construction with steel backing for maximum strength
  • Designed for high-performance and racing applications
  • Compatible with GM small block V8 engines: 262, 267, 302, 307, 327, and 350 CI
  • Complete main bearing set for full crankshaft support

King's pMaxKote polymer coating provides excellent protection during initial engine startup and reduces friction throughout the bearing's service life. This advanced coating technology helps prevent galling and scuffing while allowing for faster, safer engine break-in. Ideal for engine rebuilds, performance upgrades, and racing applications where reliability and durability are critical.

Thank you for the reminder email about the item in my shopping cart.

Really helpful and great prices!!! Quick Delivery

Quick and easy!

great sale

I did not get a final chance to see the order total with shipping +coupon applied. Order was 105+11.95 shipping -20offshipping-so should have been 96.95, but never saw the final price. The fix for this would be to show the final price before customers click pay. Product and shipping time were as expected.

Ordering the product was easy and rep. Was helpful! The product was shipped fast and came a little messed up in package but complete to my knowledge.

So far autoplicity has been a great shopping experience.
