How To Confirm Fit of Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box On Keystone Cougar

Question:

Hello, I have several questions about the GenY Gooseneck Pin Box adapter for my 2014 Keystone Cougar 337FLS 1, Do I need the Shim Kit for that Trailer? 2. What is the best way to attach the safety chains to that unit? 3. Is there a Lock to prevent the camper from disappearing from storage to fit in that coupler?

The Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box part # GY58GR is designed for the most common pin box pattern which is a Lippert 1621/1621HD. In order to confirm fit you'll have to reach out to the trailer frame manufacturer, Lippert, with the serial number off the pin box brackets. We aren't able to look up this info for any one particular trailer unfortunately.

The shim kit you referenced part # GY76FR is for Lippert 1116 pin boxes. For a lock, we have the Gen-Y Manual Latch Gooseneck Coupler Lock part # GY89FR. There are cutouts on the side of the adapter to attach the safety chains.
