About this part

Product Details

This is the Gates K120903 V-ribbed belt, specifically made for 2004 through 2007 Peterbilt 379 trucks equipped with the Cummins ISX diesel engine. This belt is crucial for keeping your fan and alternator spinning correctly, which means your engine stays cool and your electrical system stays powered.

Gates is a well-known name in belts, and this one is built to handle the demands of a heavy-duty diesel. It's a standard V-ribbed design, meaning it has multiple grooves that grip the pulleys securely to prevent slippage, even under heavy load. Proper belt tension and alignment are key during installation to ensure it lasts as long as possible and performs as expected.
