Question:
I have a 2018 voltage 3605. It has the lippert 1621hd kingpin box. Im trying to find a shorter pin box with same weight rating. Im using a Anderson hitch now but have to turn it 180 degrees so I dont hit the bed rails of truck when I turn. The Anderson has a 4inch setback if in forward position. I want to buy the Curt crosswing that has a 5inch set back. What pin box would work in this situation?

A shorter pin box will reduce your turning clearance by bringing your trailer in closer so you don't want to do that. The longest pin box we have that fits a 1621HD bolt pattern is the Curt Air Ride 5th Wheel Pin Box item # LC158778. The center of the king pin sits 27-3/8" from the back mounting bolts and 19-1/2" from the front one.
The issue is that the Curt Air Ride 5th Wheel Pin Box item # LC158778 will not work with the Anderson because it's incompatible with gooseneck adapters. However, it is compatible with the Curt CrossWing Lightweight 5th Wheel Trailer Hitch item # C86JR that mounts to industry standard rails. If you're not using 5th wheel rails then disregard everything I have said about the Curt Air Ride 5th Wheel Pin Box item # LC158778 because you can't use it.
The Lippert 1621HD 5th Wheel Pin Box - 18,000 lbs item # LC1191151 you were looking at is our only other option for a replacement pin box and the king pin on it sits 25-5/8" from the back mounting bolts and 17-3/4" from the front ones. It works with gooseneck adapters and standard 5th wheel hitches that mount on rails or puck systems.
