Clevite MS-981A-10 Engine Crankshaft Main Bearing Set

The Clevite MS-981A-10 Engine Crankshaft Main Bearing Set delivers the durability and dependability that professional engine builders and mechanics have trusted for decades. This precision-engineered bearing set is designed to provide reliable protection for your engine's crankshaft under demanding operating conditions.

Key Features:

• Bi-metal aluminum construction with 100% lead-free aluminum silicon alloy
• 60% more silicon content than comparable competitive bearings for superior performance
• Enhanced journal surface conditioning reduces break-in time and wear
• Exceptional seizure resistance protects against catastrophic engine failure
• Superior wear resistance extends bearing life and engine durability
• Precision manufacturing ensures proper clearances and fit

Clevite's advanced bi-metal bearing technology combines a steel backing with a specially formulated aluminum silicon bearing surface. The increased silicon content improves the bearing's ability to condition and polish crankshaft journal surfaces during operation, resulting in reduced friction and improved oil film retention. This makes the MS-981A-10 bearing set an excellent choice for both stock rebuilds and performance applications where reliability is paramount.
