Found an old thread with a good pic of all the Indy bushing options.
Good Bushings

Then the info I posted in the Independent bushings thread, so it is all in the same place:
https://www.slapmagazine.com/index.php?topic=118963.0Here is my run down on the Indy bushings, from using them as well as setting them up for friends and people in the shop but then skating their boards as well, so I have had a chance to see what all of them are like, not just on the first day but after they have broken in nicely too.
The white "super soft" ones are 78 duro and so very mushy feeling all round for me (normal adult size and weight) so I really only recommend them for very small lightweight skaters, or those who want trucks that almost feel like there are no bushings.
The red 88s, as said seem harder than even the blue 92s but have different properties to the blue or black ones, so it is a bit funny as the older red ones are way softer than the newer red ones.
The aftermarket orange 90 duro bushings are by fay the best for any normal person, which give a lot more than the red 88s oddly enough, especially the conical shaped ones, but I have all of them and the cylinder works fine as well.
The blue 92 duro are about my favourite, but with the low top option or cut down tops, if they are the normal ones, which are just a bit firmer and more stable, but with lower heads, I can have the trucks a bit more loose, while still having more stability than the softer options.
Black 94 duro hard bushings are firm but still compress enough for turning for heavier skaters, which in turn can be more a wheelbite issue as well, given some people want tight trucks and think these will be what they want. If tightened too much, they will have more issues than if they had harder bushings to begin with, as they don't bounce back or stay compressed more than they should.
Yellow 96 duro super hard or whatever they call them still turn but are very stiff, so pretty much the true medium hard option really, but again when people who want no turn and tight trucks get them, then tighten them down too far, then have issues with them as they think they are going to be harder than they are.
Also just to throw in thoughts on the Indy stock bushings, no matter which colour, 90 duro, a bit soft and squishy to start with but they firm up a fair bit with normal use, so while left at kingpin nut top of kingpin, they will be way more loose than most of the other bushings, apart from the white aftermarket 78s.
The stock ones used to be rubbish and would blow out or have all sorts of issues in older stage Indy trucks, but nowdays they are actually really good and I have recycled many stock sets that were taken out right from new (when people put in other bushings right away) then put them into other trucks when people have had issues with their own bushings and almost all of them have said how well they work, including putting the stock Indy white ones into Ace trucks I have had set up and people thought they turned better than the stock Ace bushings.
They are by no means the be all and end all of bushings, but they definitely work well, when worn in and not tightened down to start with or skated pretty much at factory set kingpin nut or a bit below.
