Clevite MS-2216A-.25MM AL-Series Engine Crankshaft Main Bearing Set 0.25mm Undersize

The Clevite MS-2216A-.25MM is an AL-Series engine crankshaft main bearing set designed as a direct replacement for engines requiring a 0.25mm (0.010 in.) undersize crankshaft bearing. Built on Clevite's proven AL-5 aluminum-silicon bimetal platform, these bearings deliver reliable performance for OEM-style rebuilds and mild performance applications.

Clevite AL-Series bearings feature a 100% lead-free aluminum-silicon alloy composition engineered with 60% more silicon than comparable competitive replacements, providing superior conditioning of crankshaft journal surfaces and greater seizure and wear resistance. The bimetal construction pairs a steel backing with an aluminum bearing surface for an optimal balance of strength and conformability — particularly well-suited for engines with cast crankshafts.

Key Features:

• AL-5 aluminum-silicon bimetal bearing material — 100% lead-free
• 0.25mm (0.010 in.) crankshaft undersize
• Half-grooved upper bearing for proper oil distribution
• Stock thrust bearing oversize
• Manufactured to meet or exceed OE specifications
• Carefully chosen eccentricities tailored to the application for solid, reliable performance

Clevite AL-Series main bearings are recommended for most engines using a cast crankshaft and are a trusted choice among professional engine builders for OEM-style rebuilds and mild performance applications. Cross-reference: MS-2216A-.25MM, UPC: 027067649560.
