Description

The King Engine Bearings MB5293MC030 is a set of main bearings designed for LS/LT engines. These bearings feature a bi-metal, aluminum silicon alloy construction with a polymer coating. They are grooved with a 1/2 style and are sold as a set of five.

The MC series bearings incorporate a nano-composite polymer coating, K-340, developed by King. This coating adds up to 0.0002 inches of thickness and is designed to preserve surrounding parts, even during oil starvation or metal-to-metal contact, due to superior anti-seizure properties and enhanced wear resistance.
