Product Details

The King Engine Bearings MB4272XP is a complete main bearing set engineered for the Holden Alloytec 175 and Alloytec 190 V6 engines. Designed as a direct-fit replacement or performance upgrade, these bearings deliver superior durability and reduced friction compared to standard OEM bearings.

King's XP (Extra Performance) Series bearings feature the proprietary pMaxKote polymer coating — a dry-film overlay that dramatically improves wear resistance during cold starts, oil starvation events, and high-load conditions. This makes the MB4272XP an excellent choice for both street-driven vehicles and performance builds using the Alloytec platform.

Key Features:

  • Direct replacement main bearing set for Holden Alloytec 175 and Alloytec 190 V6 engines
  • XP Series pMaxKote polymer overlay for enhanced wear resistance and reduced friction
  • Tri-metal construction: steel backing, copper-lead intermediate layer, and precision overlay
  • Engineered to OEM tolerances for drop-in fitment
  • Improved fatigue strength and load-carrying capacity over standard bearings
  • Superior corrosion resistance and compatibility with modern synthetic engine oils
  • Manufactured to strict quality standards with tight dimensional tolerances

King Engine Bearings is a globally recognized manufacturer trusted by OEM builders and professional engine builders worldwide. The MB4272XP is the ideal choice for engine rebuilders seeking a performance-grade main bearing set for the 3.6L Alloytec V6 engine family.
