pMax-Black™ tri-metal bearings for race applications
The conrod and main bearings are elementary components in the engine. The price of replacement parts alone is low, but replacing the bearings is very time-consuming.
We therefore recommend the best technical solution, namely modern three-material bearings.
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 Engine Bearings 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.
The 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.
