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, which is a unique tri-metal structure that is 24% harder than any other conventional tri-metal race bearing. King's XP-Series bearings are ideal for performance racing. King's pMaxKote contains ceramic nano-composite particles that function as a fourth layer to enhance wear resistance. The coating does not change the bearings original precision wall thickness and adds no additional thickness.
