Description

Part #: MS829P

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.

MIA's Description

The Clevite MS829P P-Series Main Bearing Set is engineered for Big Block Chevrolet engines (396, 402, 427, 454, and 502 C.I.D.). These bearings are part of the Clevite 77 series, known for their durability and performance. They feature a hardened steel back and a thin overlay for better seating, with enlarged chamfers for improved crankshaft fillet clearance. The P-Series bearings are ideal for engines operating in the medium to high RPM range. This specific set is for standard size shafts.
