MAHLE MS-2042P P-Series Engine Crankshaft Main Bearing Set

The MAHLE MS-2042P is a Clevite P-Series Tri-Metal Crankshaft Main Bearing Set designed for Nissan four-cylinder engines with displacements of 1952cc, 2187cc, and 2389cc produced from 1974 to 1989. As part of the trusted Clevite 77 bearing family, the P-Series is engineered to deliver exceptional performance in both street and high-performance rebuilds.

Key Features:

• Tri-Metal Construction: Built with a hardened steel backing for structural support, a cast copper-lead lining to handle the demands of engine operation, and an electroplated babbitt overlay on the running surface for optimal bearing-in characteristics
• Higher Eccentricity & High Crush Factor: Engineered to compensate for high load factors and distortion common in high-revving engines
• Full-Circle Oil Grooves: Oil grooves on most applications extend around both bearing halves for improved lubrication and oil film distribution
• Upgrade Over Bimetal Bearings: The Tri-Metal design provides increased load capacity, making it a direct upgrade from standard OE bimetal engine bearings
• Conformability & Embedability: Delivers a superior combination of conformability, embedability, fatigue resistance, and slipperiness not found in OE or competitive bimetal alternatives
• Versatile Application: Suitable for stock OE replacements as well as demanding applications including heavy-duty use, motorsports, and street performance builds
• Alternate Part Number: MS-2042P-25MM (25mm oversized variant also available)
