There is not a cross reference for 5th Wheel RV's that allows me to look up what pin box you have on your Keystone Raptor. To replace your pin box you need to know what bolt pattern you have, this is expressed as a 4 digit number. Please look on the currently installed pin box for identification markings/stickers to discover what pin box you currently have. Note the linked article that will step you through how to measure the bolt pattern if there are no identifying markings to determine what is installed. Once we know the pin box bolt pattern we can identify a replacement that will work.

For example, the Reese Sidewinder 5th Wheel King Pin with Rotating Turret, # RP34FR that you linked to, fits Fabex/M&M 663 and 665 models as well as the Lippert 0719, 1621 and 1621HD models. It will also fit the Lippert 1716 and 0115 with use of a spacer kit.
