King Engine Bearings MB5724XPC0.5 Performance Main Bearing Set Oversize - 0.5mm

The King Engine Bearings MB5724XPC0.5 is a high-performance main bearing set designed for GM 6.6L Duramax diesel engines requiring 0.5mm (0.020") oversize bearings. This premium XPC Series bearing set features King's revolutionary pMaxKote coating technology, delivering race-proven durability for demanding diesel applications.

XPC Series Advanced Technology:

• Tri-metal copper-based construction with pMaxBlack overlay for enhanced load capacity up to 17,000 PSI
• Factory-applied pMaxKote nano-composite polymer coating provides superior seizure and wear resistance
• Ceramic nano-composite particles function as a fourth protective layer without adding bearing thickness
• Enhanced protection during oil starvation and metal-to-metal contact scenarios
• Optimized eccentricity and crush height for improved load distribution

Precision Engineering:

• 0.5mm (0.020") oversize outer diameter for machined or worn engine blocks
• Industry-leading wall thickness tolerances with shells matched to 0.0001"
• Enlarged, chamfered oil holes for improved lubrication flow
• Medium eccentricity design enables optimal load distribution

King Engine Bearings has specialized in bearing manufacturing since 1960, and the XPC Series represents their most advanced race-grade bearing technology. This set is ideal for high-performance Duramax builds, heavy-duty applications, and engines requiring oversized bearings due to block machining or wear. Set includes 5 pairs of main bearings.
