MAHLE CB-1385A-.25MM(6) Engine Connecting Rod Bearing Set 0.25mm Undersize

The MAHLE CB-1385A-.25MM(6) is a complete connecting rod bearing set designed for Ford 3.0L V6 (183 CID) engines produced from 1986 to 1995. This set includes six (6) individual rod bearing shells machined to a 0.25mm undersize specification, making it the correct choice for engines with reground or reconditioned crankshafts requiring an undersize fit.

MAHLE is a globally recognized OE-level supplier of engine components, and these bearings are manufactured to meet or exceed original equipment standards for dimensional accuracy, surface finish, and load capacity.

Key Features:

• Undersize: 0.25mm undersize for use with reground crankshaft journals
• Set Quantity: Includes 6 bearing shells (complete set for a 6-cylinder engine)
• Construction: Bi-metal aluminum construction for excellent wear resistance and conformability
• OE-Quality: Manufactured to original equipment specifications for precise fitment and reliable performance
• Application: Ford 3.0L V6 (183 CID) engines, 1986–1995
• Part Number: CB-1385A-.25MM(6) — also referenced as CB1385A25MM6

These connecting rod bearings provide the critical wear surface between the connecting rods and the crankshaft rod journals. Replacing rod bearings with correctly sized undersize bearings during an engine rebuild helps restore proper oil clearances and extend engine life. Always verify crankshaft journal diameter before selecting bearing size.
