Clevite MS-2351A-.25MM Crankshaft Main Bearing Set Undersized

The Clevite MS-2351A-.25MM is an undersized crankshaft main bearing set engineered for precision engine rebuilds requiring 0.25mm undersize bearings. This bearing set provides a complete solution for engines with crankshaft journals that have been machined to accommodate undersize bearings.

Key Features:

• 100% lead-free aluminum silicon bi-metal construction for superior durability
• 0.25mm undersize for reground crankshafts
• 60% more silicon content than comparable competitive bearings for enhanced performance
• Advanced journal surface conditioning reduces wear and improves longevity
• Exceptional seizure resistance under high-load conditions
• Improved wear resistance for extended bearing life

Clevite's bi-metal bearing technology combines a steel backing with a lead-free aluminum silicon alloy surface layer, delivering the optimal balance of strength and protection. The higher silicon content creates a harder, more wear-resistant bearing surface that conditions the crankshaft journal over time, promoting smoother operation and reduced friction. Ideal for professional engine rebuilders and performance applications where reliability is critical.
