Engine & Performance Warehouse MS2022P020 Crankshaft Main Bearing Set Undersize - 0.020

The Engine & Performance Warehouse MS2022P020 is a crankshaft main bearing set ground to a 0.020" undersize specification, designed for use in engines with reground or worn crankshafts requiring undersized bearing clearances. This set is an essential component in engine rebuilding and reconditioning applications where standard-size bearings are no longer suitable due to crankshaft journal wear or machining.

Key Features:

• 0.020" Undersize — engineered for use with crankshafts that have been machined 0.020" below standard journal diameter
• P-Series tri-metal construction — increased load capacity compared to bi-metal designs, making it suitable for demanding OE replacement, heavy-duty, and performance applications
• Full bearing set — includes all main bearing shells required for a complete crankshaft installation
• Precision manufactured — meets or exceeds OE dimensional specifications for proper oil clearance and crankshaft end play
• Suitable for street performance, heavy-duty, and motorsports rebuilds where reliable load-bearing capacity is critical

This main bearing set is ideal for professional engine rebuilders and machine shops performing crankshaft reconditioning work. Proper oil clearance and crankshaft end float must be verified during installation to ensure long-term durability and engine reliability.
