Perfect Circle CB1814P25MM Connecting Rod Bearing Set .25mm Undersize Ford 6.0L Powerstroke

The Perfect Circle CB1814P25MM is a precision-engineered connecting rod bearing set designed specifically for 2003-2007 Ford 6.0L Powerstroke diesel engines. This .25mm undersize bearing is part of the renowned Clevite P-Series line, manufactured under the MAHLE/Perfect Circle brand family, delivering OE-quality replacement performance for engine rebuilds.

Key Features:

• Tri-metal construction with hardened steel backing for superior strength and support
• Cast copper-lead alloy substrate engineered to withstand high loads and stress
• Electroplated babbitt overlay (approximately 0.001-inch thickness) provides excellent conformability, embedability, and low-friction operation
• .25mm undersize specification for engines with reground crankshafts or worn journals
• High crush design ensures maximum bearing retention and optimal contact
• Suitable for stock replacement applications and engines with demanding use requirements

Perfect Circle P-Series bearings represent proven tri-metal technology trusted by professional engine builders for decades. The steel-backed construction provides essential rigidity, while the copper-lead lining absorbs operational stresses and the babbitt overlay delivers the slippery, conformable surface needed for reliable journal protection. This bearing set is ideal for restoring proper clearances during engine rebuilds where crankshaft machining has been performed.

Application Note: This bearing set is intended for engines requiring .25mm undersize bearings due to crankshaft journal machining. Verify journal dimensions before installation to ensure proper bearing clearances.
