Hey Kris, the Curt Helux cushioned pin box part # C65MJ that you referenced is approved for use on Lippert RV frames so it would work great and not void any warranties. This is designed to replace the Lippert Rhino pin box. Is that what you have? I wasn't able to determine for sure that is the style pin box your KZ would have came with.
