Clevite MS-2355A-.25MM Engine Crankshaft Main Bearing Set

The Clevite MS-2355A-.25MM is an undersize crankshaft main bearing set designed for precision engine rebuilds requiring 0.25mm undersize bearings. This complete bearing set provides the critical interface between your engine's crankshaft and block, ensuring proper lubrication and load distribution.

Key Features:

• Bi-metal aluminum construction with 100% lead-free aluminum silicon alloy
• Engineered with 60% more silicon content than competitive replacements for superior journal conditioning
• Enhanced seizure resistance protects against bearing failure during high-stress operation
• Improved wear resistance extends bearing life and maintains proper oil clearances
• 0.25mm undersize specification for machined crankshafts
• Precision manufactured to OEM tolerances for reliable fitment

Clevite bearings carry on a decades-long tradition of durability and dependability in engine rebuilding. The advanced aluminum silicon formulation conditions crankshaft journal surfaces during operation, creating a smoother interface that reduces friction and wear over the bearing's service life.
