Question:

Expert Reply:
Yes, it is Mike. The Gen-Y Hitch Shock Absorbing 5th Wheel Pin Box item # GY68GR is designed to fit a Lippert 1621/1621HD pin box. It has a 30,000 lbs towing capacity and a pin weight capacity range of 2,000 lbs - 4,500 lbs. This torsion pin box is designed to absorb road shock before it gets transferred to your trailer.
What kind of pin box do you currently have on your 5th wheel trailer and do you know what bolt pattern it has?
