King Ford EcoBoost 3.5L V6 Performance Main Bearing Set - Bi Metal MB4570MC Fits 2011-2020 Models

The King MB4570MC performance main bearing set delivers bi-metal construction for Ford 3.5L V6 EcoBoost engines in F-150 Explorer Expedition and more. These bearings protect crankshaft journals with high load capacity during boosted operation. Built for reliability in daily driving and track use they ensure smooth rotation and extended engine life.

Key Features

  • Bi-Metal Build: Steel backing bonded to lead-tin-copper overlay resists fatigue and handles extreme pressures in EcoBoost applications
  • Optimized Oil Clearance: Promotes full-film lubrication reduces drag and supports high RPM without metal-to-metal contact
  • Precision Tolerances: Machined to micron levels for drop-in fit minimizes runout and accelerates break-in
  • High Tensile Strength: Withstands boost-induced loads prevents wiping and maintains oil film under stress
  • Enhanced Chamfers: Large radii improve oil entry into journals boost flow and cool bearings effectively

Product Notes

  • Standard size for stock crankshaft journals verify measurements before install
  • Apply assembly lube during setup for initial protection
  • Compact packaging fits standard parcel service no freight needed

Installation Notes

  • Professional installation recommended.
  • Clean journals thoroughly and plastigage check clearances post-install
  • Matches OEM hardware torque to Ford specs
