Is a Spacer Kit Needed to Install Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter

Question:

I do not have access to my RV and would like to know if I need spacer plates when changing the pin box with a Reese 20K #94720 goose box on an Alliance Valor 36v11?

The Reese Goose Box 5th-Wheel-to-Gooseneck Air Ride Coupler Adapter # RP85FR is designed to replace Lippert 1621, 1621HD and 0719 pin boxes. A spacer kit is not required if you have one of these pin boxes on your Alliance Valor 36v11. The # RP85FR will also work with the Lippert 1716, but will require the # RP97FR spacer kit for installation.

You will need to verify which pin box you currently have in order to determine if this fits and you need the spacer kit or not. This can typically be found on a sticker on your pin box. If the sticker has faded or is missing you may also be able to contact the manufacturer to find out what you have using the VIN number. The only other option is to measure the bolt pattern on your pin box once you are able to access it again.

I have attached a helpful article which outlines the steps to measure your bolt pattern for your reference.
