Lippert Pin Box Number for Gen-Y Shock Absorbing 5th Wheel to Gooseneck Hitch


Hello, I am interested in switching to Gen Y hitch on my fifth wheel trailer but I cant figure out which Lippert pin box model that I have on my trailer. The sticker only gives me the Serial #S005901105 and the Item#2020219775. Can you help me with this? Thanks!

I just got off the phone with Lippert and you have a 1621 HD pin box. To upgrade your current pin box to a Gen Y you will want the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box - Lippert 1621/1621 HD - 21K - 3.5K TW item # GY58GR. This shock-absorbing pin box works with your gooseneck hitch to give a smooth ride while you tow your fifth-wheel trailer. The all-in-1 box has no air bags to refill or small parts to replace. The auto-latch allows for easy hookup. It has a pin weight scale built in to help you balance your trailer.

For a Goosebox that is Certified by Lippert to not void any manufacturers warranties you will want the Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter - Lippert 1621 and 0719 - 20,000 lbs item # RP94720. I saw you were looking at this one and wanted to let you know about the options for it. The fully enclosed air bag and dual shock absorbers provide cushion and absorb road shock. It has been endorsed by Lippert Components Inc. and will not affect the warranty on their trailer frames.
