Those measurements, along with the included tensioner assembly reference 38157, make 90K-38157A a practical choice when servicing the serpentine drive on Ram 2500 and Ram 3500 trucks.

Common Problems This Kit Can Address

• Worn or stretched serpentine belt
• Loss of proper belt tension
• Belt noise from aging accessory drive components
• Uneven belt tracking caused by a tired tensioner

Installation Notes and Tips

Verify the vehicle is a 1994-2002 Dodge Ram 2500 or Ram 3500 with air conditioning before ordering. Confirm belt routing and compare the existing tensioner and belt dimensions to the listed specifications for 90K-38157A. Inspect pulleys and accessory drive components during service so the new belt and tensioner can operate correctly after installation.
