1. Since metal to oil heat transfer is very efficient as compared to metal to air, the wet clutch is much better heat exchanger. Thus a wet clutch can tolerate a longer engagement time.

2. Wet clutch has a longer life then the dry type.

3. Wet clutch as applied to trucks have lower torque peaks in the drive train.

4. Due to lower coefficient of friction for friction materials operating in oil, the wet clutch has lower torque capacity as compared to the dry type. Comparing commonly used wet and dry friction materials in a clutch of the same diameter and clamping force, the wet clutch will have only 30 to 50% of the torque of the dry clutch.
