Rod Bearings, HP-Series, .001" undersize, Bi-metal, Silicon Aluminum, Chevy, Small Block, Set of 8
King HP-Series rod bearings were developed mainly for drag race applications needing a material harder than the babbit top layer. These applications demanded a structure that could withstand high loads for short durations and still offer higher embeddabilty and compatibility. In response, King developed the HP-Series featuring the Alecular metal structure.
The HP-Series is also suited for many performance applications with nodular cast iron crankshafts, such as street, strip, and some levels of Circle Track racing.
HP-Series bearings are particularly suitable for the following cases:
* When a tri-metal bearing's babbit overlay extrudes over the sides, migrates to one end, or is physically removed by the crankshaft
* When the intermediate layer of a tri-metal bearing is exposed, damaging the crank journal and requiring expensive grinding or replacement
* When contaminants enter the oil stream, scratching and damaging the crankshaft journals
