Clevite MS502P10 P-Series Main Bearing Set Undersize - 010

The Clevite MS502P10 is a P-Series main bearing set designed for high-performance and demanding engine applications. Part of the oldest members of the Clevite 77 bearing family, P-Series bearings are intended for high-revving engines, making them ideal for motorsports, heavy-duty use, and street performance builds.

Advanced Tri-Metal Construction:

P-Series bearings are constructed of tri-metal cast copper lead, featuring a steel back for support, a cast copper lead lining to withstand engine operation loads, and an electroplated babbit overlay on the running surface. This advanced design delivers superior conformability, embedability, and fatigue resistance compared to original equipment bearings.

Key Features:

• .010 inch undersize for reground crankshafts
• Higher eccentricity and high crush factor to compensate for high-load factors and distortion
• Oil grooves extend all the way around both halves for better oiling
• Increased load capacity of the Tri-Metal design makes it a suitable upgrade from Bi-Metal engine bearings
• Reduced overlay thickness to prevent overlay fatigue

Ideal for rebuilding engines where more demanding use is anticipated, such as heavy duty, motorsports, or street performance. Combining the legendary CLEVITE bearing brand for domestic applications with MAHLE Performance, CLEVITE engine bearings have been winning NASCAR sanctioned races since the very first NASCAR championship in 1948.
