MAHLE MS-804P-10 P-Series Tri-Metal Engine Crankshaft Main Bearing Set -.010" Undersize

The MAHLE MS-804P-10 is a P-Series Tri-Metal crankshaft main bearing set ground to -.010" undersize, engineered for engine rebuilds where durability and performance are required. Part of the legendary Clevite bearing lineup now offered under the MAHLE brand, the P-Series is the most versatile replacement bearing available and is suitable for a wide range of OE applications.

Key Features:

• Tri-Metal construction — three-layer design featuring a precision steel backing, copper-lead alloy intermediate layer, and an electroplated white metal "babbitt" surface layer
• High load capacity — capable of carrying maximum loads of up to 12,000 psi
• High eccentricity — accommodates bore distortion for improved fit and performance
• High crush factor — ensures positive seating and bearing retention in the housing bore
• Grooved lower mains — maintain 360-degree oiling for consistent lubrication
• Hardened steel backing — provides greater structural strength under heavy loads
• -.010" undersize — designed for use with crankshafts that have been reground .010" under standard diameter

The MAHLE/Clevite P-Series delivers a superior combination of conformability, embedability, surface slipperiness, and fatigue resistance compared to standard OEM and competing bi-metal bearings. This makes the MS-804P-10 an excellent upgrade for stock engine rebuilds as well as heavy-duty, street performance, and motorsports applications.
