MICHIGAN 77 MS2328P25MM P-Series Main Bearing Set Undersize - 0.25mm

The MICHIGAN 77 MS2328P25MM P-Series Main Bearing Set is a high-performance engine crankshaft bearing kit designed for precision engine rebuilds. This set features a 0.25mm undersize specification, making it ideal for crankshafts that have been machined or require precise fitment.

Key Features:

• P-Series tri-metal construction with TM-77 bearing material for enhanced durability and load capacity
• Full-grooved design maximizes oil flow to bearings for improved lubrication
• High crush design ensures maximum retention in the bearing bore
• Reduced overlay thickness prevents overlay fatigue and hen tracking
• Higher eccentricity narrows bearing contact patterns and increases oiling to rod bearings
• Steel-backed with copper-lead alloy intermediate layer and electroplated lead-tin-copper overlay

This bearing set is ideal for rebuilding engines where more demanding use is anticipated, including heavy-duty applications, motorsports, and street performance builds. The P-Series design offers superior performance compared to standard bimetal bearings and is suitable for most OE replacement applications requiring 0.25mm undersize bearings.
