Part #: MS804P20

Ideal for rebuilding engines where more demanding use is anticipated, such as heavy duty, motorsports, or street performance. As it is the most versatile replacement, Clevite engine bearing P-Series is suitable for most OE applications. Due to the increased load capacity of the Tri-Metal design, it is a suitable upgrade from Bi-Metal engine bearings.
