Victor MS2232A10 Engine Crankshaft Main Bearing Set -0.010 Undersize AL-Series

The Victor MS2232A10 is an AL-Series engine crankshaft main bearing set designed as a direct OE replacement for GM and Saturn four-cylinder Ecotec engines. This set is the -0.010" undersize variant, intended for use during engine rebuilds where the crankshaft journals have been machined to the first undersize specification.

Key Features:

• AL-5 aluminum bearing material — softer and more conformable than steel-backed bearings, providing excellent break-in characteristics on cast crankshafts
• -0.010" undersize (size code: A10) — engineered for crankshafts ground to the first undersize
• Maximum wall thickness: 0.1641 in.
• Maximum housing bore: 2.5229 in. | Minimum housing bore: 2.5223 in.
• Carefully chosen eccentricities tailored to application for solid, reliable performance
• Suitable for OEM-style rebuilds and mild performance applications
• Recommended for engines equipped with a cast crankshaft

This bearing set carries the Clevite/MAHLE cross-reference part number MS-2232A-10 and is engineered to restore proper crankshaft-to-block clearances during a bottom-end rebuild. The aluminum construction delivers superior conformability and seizure resistance, making it an ideal choice for restoring long-term engine reliability.
