Is true that the problem with inverted kingpins is that the nuts are always getting loose??
Some people don't seem to have any problems at all with any inverted kingpin assembly, but most people who have run inverted kingpins for a while find sooner or later they have issues.
Others often find that the whole nut assembly in the baseplate gets loose, so not so much the nut itself, but the mounting around it ovals out, so the kingpin moves side to side, almost to the point of it feeling like bushings are not doing their job or the pivot cup is blown out, which in both cases it was not, on the set I had a roll on.
The solid and heavy landings in various tricks, be it crooks or whatever can cause more side to side pressure which then causes the kingpin to move a lot more than a fixed kingpin in a regular truck, so once it starts to move a bit, even slightly, then every hard landing to one side or other makes the kingpin move back and forth side to side, in the same way that deck bolts that are loose will oval out deck bolt holes in truck baseplates, which I think a lot more people have seen over any given period of time.
I found that when the kingpin was in fully, up to the last thread so it could not go any further, it seemed to hold a lot better, but some others were running the kingpin barely in, which didn't lock into the nut in the baseplate in the same way that a regular kingpin nut sits only half on and then loosens by itself.
Also consider how often some people swap out their kingpin nuts like it is nothing. You can't do this on an inverted kingpin nut which is fixed into the baseplate, so when the nyloc starts to go, they have to use some locking product (like glue) or find some other way to keep the kingpin from moving in the baseplate nut.

Funny old thing, but I guess some bushings do just have different properties. Even some of these ones I have are so much darker in colour, some very cloudy or almost murky orange, compared to the semi translucent orange of brand new ones.
Were all the ones you used the newer ones with rings on the inside of them, or older ones with the flat poured bubble look to the face of them?
I've been experiencing these inconsistencies between two sets of new (rings) bushings too. Was not as obvious as with old vs. new, but one pair before current I could never get the bushings work like I wished, had to take bushings from my old trucks. On the other hand, current pair worked almost out of the box, after a one break-in session.
Yeah I recall you asking or getting frustrated with bushings before. It is a funny thing, but who knows if it is certain compounds, or other factors that contribute to things working or not working with any given products.
I still find that a lot of people swap out stock bushings, no matter what trucks, so I do end up with a lot more unused or very lightly used stock bushings than I can ever find uses for, but it helps when someone comes back cause they have blown something out so I can easily just put in some others for them, or at least help them with used / spare parts I have round the place.
I can be such a stickler for trying to make some things work too - thinking "I can fix this somehow" but some things, I should just give up on and leave them, more than mess with them until they just drive me nuts, but in saying that, more often than not, I can usually find a way to fix something or at least make it work, which is better than just throwing the things out.
