The nozzles in particular are aftermarket items. Universal doesn't make them and neither does Kubota. They're actually made by Denso and the wholesale price appears to be around thirty or forty dollars. Kubota and the independent parts suppliers buy them and add whatever markup they want. It just happens that Universals markup is about 300%. All they do is put their own label on the box. It's the same as the parts Kubota does make, Universal buys them like anyone else and relabels them. Those are very expensive labels, and that's all you're getting for the money. As long as people keep paying the price, they will keep doing it.
