Question:
I am looking for identification of my Lippert Components S/N S009627841, Item number 2021102825 hitch that is on my 2023 Heartland Cyclone 4006. I need to know the pin block number to change my fifth wheel to a gooseneck.

Hey Jeffrey,
Lippert confirmed that your pin box is a Rhino Box, so I recommend the Shocker Hitch 5th Wheel to Gooseneck Coupler Kit # SHK99YR.
You will also need the Safety Chain Kit for Shocker Hitch 5th Wheel to Gooseneck QuickAir Hitch # SHK35MR. Safety chains are required by law when towing with a gooseneck connection and these are not included with the pin box.
Which gooseneck hitch do you have on your truck?

Hey Jeffrey, how did things go with the Shocker Hitch coupler kit and safety chain setup for your Rhino Box? It’d be great to hear how the fit worked with your gooseneck hitch. Your update could make it easier for the next person with the same setup.
