All I can say it make sure you have it packaged well. I normally won't ship something like a roof rack but then being just outside of NYC, there are a lot of Rover owners within driving distance willing to take a ride up to CT. I shipped an SD rack just under a year ago to someone who insisted on taking all the responsibilities involved in getting it down south. They made the arrangements, I palletized it and wrapped it as securely as possible. Nevertheless, when it got there it was shaped like a big V and the freight company refused any claim saying the packing was insufficient. The customer had someone he knew go to town on it with a welder. I don't know the outcome but I never heard another work from him.
Without the original packaging you're always taking a bit of a risk because you never know what the carrier will deem sufficient for packaging to prevent damage in transit.
