Clevite MS-1983A-10 Engine Crankshaft Main Bearing Set

The Clevite MS-1983A-10 is a precision-engineered main bearing set designed to deliver reliable protection for your engine's crankshaft. This complete bearing set provides the essential interface between the crankshaft and engine block, ensuring smooth rotation and optimal oil film thickness under demanding operating conditions.

Key Features:

• Bi-metal aluminum construction with 100% lead-free aluminum silicon alloy
• Enhanced silicon content (60% more than competitive bearings) for superior journal surface conditioning
• Exceptional seizure resistance protects against bearing failure during high-load conditions
• Advanced wear resistance extends bearing life and maintains proper clearances
• Precision manufacturing ensures consistent bore diameter and wall thickness
• Compatible with standard and performance engine builds

Clevite bearings are trusted by professional engine builders and mechanics for their consistent quality and durability. The MS-1983A-10 main bearing set is oversized by 0.010 inch (indicated by the -10 suffix), making it ideal for crankshafts that have been machined undersize during rebuilding or repair. The advanced aluminum silicon formulation provides excellent embedability of dirt particles while maintaining the structural strength needed for high-performance applications.
