About this part

The King SI-Series Main Bearings MB 509SI are high-quality engine bearings designed by the brand King. These bearings are a crucial component for ensuring smooth and reliable engine performance. Made with precision and durable materials, they provide support and lubrication for the engine's moving parts, reducing friction and wear for a longer lifespan. Ideal for car and truck owners looking to replace or upgrade their engine bearings, these King bearings offer a reliable and efficient solution for maintaining engine health and performance.

The King MB 509SI is a set of SI-Series main bearings. Main bearings are the shells in the block and main caps that support the crankshaft on a film of oil. They are replaced during an engine rebuild, or when wear, spun bearings or low oil pressure show up.

Before you order: the listing does not name an engine or a size, so look up 509SI in the King catalog for your engine, measure your main journals, and confirm whether you need standard or undersize shells.
