Product Details

The King Engine Bearings MB557XPCSTDX 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 variants. Engineered for racing and extreme-duty applications, these bearings deliver exceptional durability and load capacity.

Advanced Tri-Metal Construction:

  • Race-grade tri-metal design with proprietary pMaxKote™ coating technology
  • Features a unique non-scaled hardening process for superior load capacity and fatigue resistance
  • pMaxKote™ ceramic nano-composite particle layer functions as a fourth protective barrier
  • Enhanced wear resistance for high-stress racing and performance environments
  • Standard size (STDX) for factory crankshaft journals

King's XP Series bearings are specifically developed for race engines and high-performance builds where maximum bearing protection is critical. The advanced coating system reduces friction and prevents metal-to-metal contact during startup and extreme operating conditions.
