King Engine Bearing was founded in 1960 to supply the highest quality engine bearings for engine builders. King manufactures all of their bearings in house, with rigorous quality checks and procedures so you get a consistent, high performance bearing.

King XP-Series rod bearings feature advanced metallurgical and geometric technologies that meet extreme performance loads. They were developed for all performance applications that use forged steel aftermarket crankshafts and produce high loads for extended periods.
