The XP Tri-Metal Racing Series


Successful race engine builders are constantly pushing the limits of load capacity to new levels. Race bearings today inevitably need to match these demands with more competitive bearings. At King Racing we met the challenge with the XP high performance bearings series.

The XP 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 forged steel aftermarket crankshafts and produce high 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.

pMaxKote- Coated Bearings
King factory applied nano-composite polymer coating

King’s pMaxKote ia a revolutionary new approach to coated bearings. This unique polymer coating is applied over King’s pMaxBlack overlay at the King factory during the bearing manufacturing process. King’s pMaxKote contains ceramic nano-composite particles that function as a fourth layer to enhance wear resistance. pMaxKote does not change the bearing’s original precision wall thickness and adds no additional thickness.

with additional:

• Seizure resistance
• Superior cavitation resistance
• Wear resistance
• Protection against oil starvation
