Construction & Design
The King main bearing set is constructed using premium bearing alloys selected for their strength, fatigue resistance, and ability to withstand high temperatures. The bearings feature a multi-layer design, typically including a steel backing, a copper-lead or aluminum alloy intermediate layer, and a soft overlay to provide excellent conformability and embedability. This layered construction helps protect the crankshaft journal from wear and damage while maintaining optimal oil film thickness.
