Victor MS2327A20 Engine Crankshaft Main Bearing Set A-Series .020 Undersize

The Victor MS2327A20 is an engine crankshaft main bearing set designed as an OE replacement for high-displacement V8 engines. Carrying the A-Series aluminum designation, this set is engineered for crankshafts that have been reground to .020" undersize, making it an essential component for engine rebuilds requiring precision sizing on worn or machined journals.

Key Features:

• A-Series Bimetal (Aluminum) Construction — 100% lead-free aluminum silicon formulation for a cleaner, more modern bearing material
• 60% More Silicon than comparable competitive replacements for superior conditioning of journal surfaces
• .020" Undersize — designed for use with crankshafts reground 0.020" below standard journal diameter
• Greater Seizure and Wear Resistance — aluminum silicon alloy delivers improved durability under demanding operating conditions
• OE Replacement Specification — meets or exceeds original equipment standards for reliable, long-lasting engine performance
• Made in USA

The MS2327A20 is a complete crankshaft main bearing set. Note: A thrust washer set is required and sold separately — refer to the applicable thrust washer part number for your application. Always verify crankshaft journal diameter with precision measuring tools before selecting bearing size.
