The Clevite MS-1949A is an engine crankshaft main bearing set designed for engine rebuild projects. This set features 100% lead-free aluminum silicon construction, offering 60% more silicon than competitive bearings for improved journal surface conditioning, seizure, and wear resistance. Manufactured from cast copper-lead, these bearings provide approximately 20% more fatigue strength compared to powdered metal processes.

The aluminum alloy is durable and interacts closely with journal surfaces for strength and longevity. They are recommended for use with nodular iron crankshafts and feature 100% bored inside diameters for precision. These bearings are manufactured to meet or exceed original equipment specifications, providing reliability for daily drivers or performance engines.
