Product Description
Dial in proper oil clearance on your common-rail Cummins with the MAHLE CB-1873AP-.25MM Connecting Rod Bearing Set. This .25 mm undersize (.010" under) bearing pair is engineered for reconditioned crank journals and fractured-cap rods used on 2003–2018 5.9L/6.7L engines. The P-Series design uses a tri-metal upper for load capacity and a bi-metal aluminum lower for stable oil film and scuff resistance—built to OE durability for daily, tow, or work duty.

FAQ
Will .25 mm undersize fit my stock crank?

How many pairs do I need?
Six pairs (one per connecting rod) for a full 6-cyl Cummins.
Do these fit both 5.9L and 6.7L?
Yes, 2003–2018 common-rail engines that use fractured-cap rods. Verify rod style before purchase.
What’s the construction?
Tri-metal upper for load capacity with a bi-metal aluminum lower shell to maintain oil film and reduce scuffing.
