King Engine Bearings MB529XPC001 Coated Tri-Metal Main Bearing Set Ford 260 289 302 Windsor

The King Engine Bearings MB529XPC001 is a pMaxKote™ tri-metal coated main bearing set engineered for high-performance and race applications in Ford Small Block Windsor engines. Designed to handle the extreme loads and RPMs generated in competition environments, this set delivers a significant upgrade over standard OEM-style bearings.

pMaxKote™ Tri-Metal Construction:

• Tri-metal structure — A unique three-layer design purpose-built for race applications, providing the strength and durability demanded by high-output engines
• Proprietary hardening process — The overlay features a non-scaled hardening process that produces superior load capacity compared to conventional bearing coatings
• Ceramic nano-composite coating — pMaxKote™ incorporates ceramic nano-composite particles as a fourth functional layer, further enhancing wear resistance and extending bearing life under race conditions
• Bulls Eye Tolerance — King bearings are manufactured to the closest wall tolerances in the industry, with all shells matched to 0.0001" for precise fitment
• Enlarged, chamfered oil holes — Main bearings feature improved oiling passages for better lubrication under high-load conditions
• Narrowed design — Optimized for use with large-radius crankshafts common in performance builds
• Undersize: 0.001" (001)

King Engine Bearings has specialized exclusively in engine bearings since 1960, bringing decades of precision manufacturing expertise to every set. The MB529XPC001 is the pMaxKote™ coated variant of the MB529 series, making it an ideal choice for builders seeking maximum wear protection in street/strip and full race Small Block Ford applications.
