Performance and Race engines are constantly being pushed to their limit.  A quality bearing needs to match these demands. King Bearings USA have have stepped up to the challange with the new XP Race series. .

The XP Race series is a line of bearings with advanced metallurgical and geometric technologies that meet extreme performance loads. It was developed for all performance applications that use factory, forged steel and billet aftermarket crankshafts and produce high power and torque loads for extended periods.

King Racing’s XP series features pMax Black™, a unique tri-metal structure that is 24% harder than any other conventional tri-metal race bearing.  pMax Black™ together with the XP geometric features are the ideal combination for performance racing. King Racings pMax overlay is strengthened by a proprietary nano-scaled hardening process that modifies the molecular structure and creates a black fatigue resistant shield. The outcome is a significant 24% increase in hardness and load capacity. reaching 18.1hv and maximum fatigue resistance of 10,200psi.

King race series bearings have exceptional accuracy (bulls eye tolerance) No need for multiple bearings to get the clearance. Accurate every time.
