Clevite MS2007P25MM - Ford Modular 4.6L Romeo Tri-Metal P-Series Main Bearings 1/2 Grooved - .010" Undersize

Recommended for naturally aspirated and mild forced induction 4.6 Engines. Will only fit the 4.6 ROMEO Iron Blocks and are not interchangeable with any other 4.6 or 5.4 Blocks. The Tri-Metal P-Series rod bearings are the oldest members of the Clevite 77 performance-bearing family. They're intended for high-revving engines, especially those where the high rpm cause the rod bores to narrow. To compensate for this distortion, they have higher eccentricity and a high crush factor.
