A bushing is a component that is used to reduce friction and wear in a truck’s suspension system. Cummins 4BT 3.9 And 6BT 5.9 Connecting Rod Bearings refers to a specific type of bushing that is designed to fit a Cummins 3.9 and 5.9 diesel. The bushing is made from durable materials such as rubber or polyurethane and fits securely into the suspension system, providing support and stability while absorbing shock and vibration. The design of the bushing helps to reduce noise, harshness, and vibration (NVH) in the cabin, resulting in a smoother ride for passengers. Over time, bushings can become worn or damaged due to exposure to harsh weather conditions or heavy usage. It’s important to regularly inspect the suspension system for signs of wear or damage and replace any worn-out bushings promptly to ensure the safe operation of the vehicle.

We carry connecting rod bearings and shell sets for Cummins 3.9 and 5.9 liter engines.
