Clevite MS307P20 P-Series Main Bearing Set Undersize - 020

The Clevite MS307P20 is a P-Series main bearing set designed for stock replacement and high-performance applications. P-Series bearings are constructed of tri-metal cast copper lead, providing excellent durability and performance characteristics for demanding engine builds.

Key Features:

• Tri-metal construction with cast copper lead substrate
• Steel backings with extra-thin overlays to prevent overlay fatigue
• Higher eccentricity and high crush factor to compensate for high-load factors and distortion
• .020 inch undersize for proper crankshaft clearance
• Full grooved design to maximize oil flow to the bearings
• Reduced overlay thickness to prevent overlay fatigue

Clevite P-Series main bearings produce a degree of conformability, embedability, slipperiness, and fatigue resistance not found in original equipment and competitive bimetal bearings. The P-Series is ideal for applications requiring enhanced oil flow and superior bearing retention in high-performance and competition engine builds.
