Perfect Circle Rod Bearing Set for Duramax Diesel Engine

Perfect Circle connecting rod bearings are made for Duramax diesel engines. They are a replacement engine connecting rod bearing (rod bearing) for engine rebuilds and overhauls. Rod bearings sit between the connecting rod and the crankshaft journal. They support a thin oil film that lets the rotating assembly run smoothly under the high cylinder pressures of a diesel.

Key Features:

• Tri-metal construction: a copper-lead alloy layer is bonded to a hardened steel back and electroplated with a white-metal babbitt running surface.
• Diesel-duty design: built for the loads and durability demands of the Duramax diesel.
• Precision-made: the bearing shells are made to fit consistently and hold stable oil clearance.
• Multiple options: the product line includes different bearing series and size choices, so you can pick the one that suits your engine build.

Replacing worn rod bearings during a rebuild helps restore proper oil clearance and protects the crankshaft and connecting rods. Choose the exact part number that matches your engine's journal and clearance requirements.
