Clevite MS-2381P-.25MM Main Bearing Set

Clevite MS-2381P-.25MM is a P-Series engine crankshaft main bearing set for rebuilds that see heavier service, including street performance, motorsports, and heavy-duty use. It is also a practical OE replacement choice for Ford Super Duty applications that need added load capacity from a tri-metal bearing design.

Key Features

• Tri-metal construction for increased load capacity
• P-Series bearing design for demanding rebuilds
• .25mm undersize specification
• Oversized housing bore O.D. resized .040" larger than stock
• Suitable for OE replacement and performance-oriented engine rebuilds
• Fits 2008-2010 Ford F-250 Super Duty and 2008-2010 Ford F-350 Super Duty

Detailed Description

This Clevite main bearing set is built for engine rebuilds where durability and load handling matter. The tri-metal bearing construction provides a stronger service profile than bi-metal designs, making MS-2381P-.25MM a solid choice for Ford F-250 Super Duty and Ford F-350 Super Duty engines used in work, towing, or street performance settings. The P-Series line is positioned as a versatile replacement for many OE applications while adding the bearing strength needed for more demanding conditions.

What It Helps Address

• Crankshaft main bearing wear during engine rebuilds
• Reduced load capacity in engines seeing heavier use
• Need for an undersize main bearing solution
• Replacement needs for Ford Super Duty engine service work
• Performance rebuilds requiring a tri-metal bearing upgrade

Installation Notes and Tips

Verify crankshaft journal size, housing bore condition, and bearing clearance before assembly. Confirm the .25mm undersize specification and the oversized housing bore O.D. requirement match the engine machining work performed. Clean all oil passages and follow the engine builder’s torque and lubrication procedures during installation.

Quality Assurance

Clevite’s P-Series bearing line is engineered for applications that demand higher load capacity than standard bi-metal replacements. MS-2381P-.25MM is intended for rebuilds where durability and consistent bearing performance are important.
