If you're looking to replace the pin box on your KZ Sportsmen then you'll first need to know the bolt pattern. Typically there's a label somewhere on it that will have an RPO or serial number that we can use to find out the bolt pattern, if it doesn't then you can use the attached guide below to determine the bolt pattern.
For example, the Curt Flex Air 5th Wheel Pin Box # LC369535 you were looking at has a 1621 bolt pattern, which is the most common. This pin box has an internal air bag that can be adjusted to fine tune your ride and help absorb road shock.
If you find the sticker with those numbers on it let me know and I can figure out the bolt pattern.
