Industrial Injection 89-02 Dodge Cummins 12V/24V H Series Rod Bearing (Std .025)

These Industrial Injection H Series rod bearings are built to a standard .025 inch undersize, meaning they're designed to fit crankshaft journals that have been machined down by that amount. This is a common practice when rebuilding an engine, especially if the original journals have wear or have been previously ground. The H Series designation points to a specific material composition and construction intended for the demands of the 12V and 24V Cummins engines found in Dodge trucks from 1989 to 2002.

When you're rebuilding the bottom end of your Cummins, the rod bearings are critical for ensuring smooth operation and longevity. They sit between the connecting rod and the crankshaft, allowing the rotating assembly to spin freely while handling significant forces. Industrial Injection has put these bearings together with materials and a design that can handle the torque and mileage these trucks are known for. Getting the right size bearing, like this .025 undersize set, is key to establishing proper oil clearance and ensuring the engine runs right after the rebuild.
