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.

Each bearing shell is precision ground and polished to ensure a perfect fit within the engine block, minimizing the risk of misalignment or premature wear. The coatings applied to the bearing surfaces enhance corrosion resistance and reduce friction, contributing to improved engine efficiency and longevity.
