MAHLE MS-2258H-.026MM Main Bearing Set for Subaru EJ Series Engines - 2.0L 2.2L 2.5L

The MAHLE MS-2258H-.026MM is a precision-engineered crankshaft main bearing set designed specifically for Subaru EJ-series engines, including 2.0L, 2.2L, and 2.5L variants. This bearing set features a #5 thrust bearing configuration and is sized at -.026MM undersize to accommodate machined crankshafts during performance builds or engine rebuilds where the journals have been ground to restore proper tolerances.

Key Features:

• Engineered specifically for Subaru EJ-series engines (2.0L, 2.2L, 2.5L displacement)
• -.026MM undersize specification for machined crankshafts
• #5 thrust bearing position configuration
• Precision-manufactured to OE specifications for reliable engine performance
• High-quality bearing material with advanced tri-metal construction
• Optimized oil clearances for proper lubrication and longevity

MAHLE bearings are manufactured using advanced materials and coating technologies to provide exceptional wear resistance, load capacity, and thermal stability. This main bearing set is ideal for engine rebuilders and performance enthusiasts working with Subaru boxer engines that require undersize bearings due to crankshaft machining. Proper installation requires verification of crankshaft journal dimensions and bearing clearances using precision measuring tools.
