The absolute best pin box to use with the B&W Companion 5th Wheel Trailer Hitch part # BWRVK3400-5W and the Custom Underbed Installation Kit part # BWGNRK1384-5W on your 2017 Ram 2500 is the Trailair Flex Air 5th Wheel Pin Box.

The Trailair Flex Air pin box has both a cushioned airbag and shock absorber. The airbag is going to act as a buffer between the trailer and 5th wheel hitch. As the airbag absorbs the shock, the shock absorber then prevents any bouncing. This unit also has a pivoting head which is going to allow it to move front to back reduce what is referred to as chucking.

If you can tell me the make and model of the pin box you have now I would be glad to make sure you get the proper replacement. The make and model is usually placed on a sticker atop the unit. The most common is a Lippert 1621 for which the correct replacement would be part # LC328492.

I have attached a demo video for you as well.
