Product Description

The **Clevite MS2199H1** is a high-performance main bearing set designed for GM LS-series V8 engines from 1997 to 2007, covering displacements such as 4.8 L, 5.3 L, 5.7 L, and 6.0 L. Built on Clevite's H-Series platform, these bearings offer excellent load capacity, fatigue resistance, and oil film stability - making them ideal for high-RPM or performance builds.

These bearings feature a tri-metal construction: a steel backing for structural strength, a copper-lead layer for contoured seating and embedability, and a thin surface overlay for a smooth rotating interface. The .001" undersize specification provides slightly tighter clearance, suitable for cranks that have been polished or require a snug fit.

The H-Series design also includes enlarged edge chamfers and a high crush factor, offering enhanced durability and reliable performance under demanding engine conditions. With no flash plating, these bearings seat precisely on the journal, ensuring consistent oil film and long-term reliability.
