Clevite MB3977P Individual Main Bearing

The Clevite MB3977P is an individual main bearing designed as a stock replacement component for engine rebuilds. This bearing is part of Clevite's P-Series line, which is engineered specifically for use with stock crankshafts in a wide range of automotive applications.

Construction and Design:

• Tri-metal cast copper-lead construction for superior durability
• Hardened steel backing provides exceptional strength and stability
• Extra-thin overlays designed to prevent overlay fatigue
• Higher eccentricity and high crush factor to compensate for high-load factors and engine distortion
• Extended oil grooves on most applications for improved lubrication

Application:

Clevite P-Series bearings are ideal for stock engine rebuilds and replacement applications. The tri-metal design combines a steel back layer with copper-lead substrate and electroplated overlay, providing the optimal balance of load capacity, conformability, and wear resistance for daily driving conditions.

What's Included:

This listing is for one individual main bearing half. For complete engine assembly, multiple bearings will be required depending on your specific engine configuration. Always verify bearing specifications and fitment before installation.
