King Engine Bearings XPC Series Main Bearing Set Oversize

King Engine Bearings XPC Series main bearing sets are premium race-grade crankshaft main bearings. They are also sold as pMaxKote coated main bearings. They are built for high-load, high-RPM performance and racing engines. Each set uses King's tri-metal construction, a pMaxBlack hardened overlay and a factory-applied pMaxKote polymer coating. The coating adds protection without changing the bearing's original wall thickness.

Key Features:

• Tri-metal construction: a strong layered structure that gives high fatigue resistance and load capacity.
• pMaxBlack overlay: a hardened overlay that resists fatigue under extreme loads.
• pMaxKote nano-composite polymer coating: a factory-applied fourth layer containing ceramic nano-composite particles and solid lubricant. It adds no thickness, so the original precision wall dimensions are kept.
• Better protection: improved seizure, wear and cavitation resistance, plus added protection during marginal lubrication or oil starvation.
• Precision geometry: King's performance design features include an oil slot for oil flow, tight wall-thickness tolerance control, and optimized eccentricity and crush height. These help stabilize the oil film and keep the bearing seated.
• Oversize options: made for engines that need a modified oil clearance or a reground crankshaft.

These bearings suit engine builders who want dependable crankshaft protection in racing, forced-induction and other high-horsepower builds. Select the child item that matches your engine and required bearing size.
