Precision built to the high standards demanded by today's rodders and restorers, these silicon bi-metal bearings are available in standard size, .010", .020", or .030" undersize.

Improves Crankshaft Finish: Silicon particles reduce/eliminate microscopic ferrite peaks on improperly ground/polished nodular cast iron crankshafts.
Wear Resistance: During engine operation, silicon particles round off crank journal high spots, reducing friction and related wear.
Improved oil clearance: Because of reduced wear, silicon bearings make it possible to maintain OE clearances over the life of the engine, which reduces operating noise, vibration, and excess oil flow.
Tolerance Control: All shells matched to ± .0001" vs. the competitions' ± .00025"
Temperature Threshold: Silicon bimetal material melts/flakes at 662° F vs. tri-metal at 365° F.
Corrosion Resistance: Defends against corrosion caused by unleaded fuels and moisture.
Environmentally Friendly: All KING silicon bimetal engine bearings are "Lead Free".
O.E. preferred material: Most O.E. engines today use and enjoy the benefits of silicon bimetal bearings.
