What durometer is the Indy stock bushing? That’s what I’m riding but I have a pair that needs an update.
Almost all normal current trucks are supposed to be 90 duro, regardless of the colour, the only ones seemingly harder were the dark deep red, almost burgundy colour that were in some pro versions, but I cannot remember which ones, something that had a lot of black on them though.
Stock bushings are a touch softer, but still work fine, if not better as replacements and come in red 88 soft, orange 90 medium, blue 92 medium hard, black 94 hard. There are white 78 super soft and yellow 96 super hard too, but you would not need to worry about those.
