Detailed Description

Part number B40212 is built for vehicles that use a serpentine-style accessory drive system and need a complete repair rather than a single-component swap. The kit is centered around a grooved black belt, an 8-groove steel pulley, and OE-quality tensioning components to help maintain proper belt tracking and system efficiency. This part cross-references Monroe Shocks & Struts (e.g., BK5351) for the same application.

For Dodge Ram 2500 and Dodge Ram 3500 applications, as well as Ram 2500, Ram 3500, Ram 4500, and Ram 5500 models, this kit addresses wear in the belt drive system with matched parts from one source. It also covers Sterling Truck Bullet 45 and Bullet 55 applications listed in the fitment data. B40212 is a practical choice when the belt, pulley, and tensioning components need to be serviced together.

What It Helps Solve

• Belt squeal caused by worn or stretched drive components.
• Misalignment that can lead to uneven belt wear.
• Vibration in the accessory drive system.
• Cracking or stretching in an aging grooved belt.
• Loss of proper belt tension from worn tensioner parts.

Installation Notes and Tips

Verify the vehicle application against the fitment list before ordering. Inspect related accessory drive components during service and replace worn parts as needed to complete the repair correctly. Follow the vehicle service procedure for belt routing and tensioner setup.
