5th Airborne Pin Box Recommendation for Trailer with 15.5k GVWR and Lippert 1621 Pin Box
Question:
Can you tell me the difference between the 5th Airborne 16k VS 21k 1621 hitches? We are planning to buy a new 5th wheel at 15,500 GVW and wondering if there is one hitch better for the application. Is there a negative affect to running the 21k hitch on a lighter trailer under 16k GVW? What advantage is one VS the other? Thank You,

Pin boxes with higher weight capacities generally are more expensive so the idea with offering a lower capacity option is to save some money while still offering a fit that will work great. If you go with an overkill pin box you really wouldn't gain anything but you also wouldn't be giving up anything except for a little more cost.
Since your trailer has a Lippert 1621 pin box and a GVWR of 15.5k the 5th Airborne you'd want is the part # 5AB-E1621-16K which has a 16k capacity. As long as you stay under 16 this will work really well.
I attached an install video for this pin box for you to check out as well.
